Advantages
Advantages
“1C-Bitrix: Virtual Machine” is an excellent solution to the problem of high-quality configuration of hosting and dedicated servers. Usually, in order to achieve high project performance, you need to configure the server software, OS, and hardware yourself. In addition, it is important to ensure safety. And in “1C-Bitrix: Virtual Machine” all these settings have already been completed. As a result, you save time and money on server deployment and configuration, on purchasing necessary equipment, on ensuring the safety of the project.
Everything is ready to go!

Saving
There are significant savings for the company:
- on deployment time;
- on equipment;
- on operating costs.
Rent
The product “1C-Bitrix: Virtual Machine” can be rented from hosting providers. You can rent a virtual machine using any virtualization technology: VMware, Parallels Virtuozzo Containers, Amazon EC2 (AMI), Open VZ, Citrix.Initially, virtualization was only program level and the advantages of virtualization were offset by a significant slowdown in work in a virtual environment. The issue was partially resolved in hardware - vendors developed instructions Intel processors VT-d, AMD-V, etc. to speed up work. However, memory and processor are not the only components, there is also a video card, hard disks and so on. and the speed of operations directly depends on the implementation of access to them. Those. Depending on the manufacturer of the virtual machine, drivers from the equipment manufacturer, and the ability of the final software to recognize virtualization, the speed of operation still depends significantly.
Different applications slow down differently in virtual reality.
In addition to the hardware costs of maintaining virtualization software, another slowing factor is the organization of the passage of time. The flow speed in the physical gland and the virtual gland are not the same. Plus, the virtual machine can be paused. The complexity of implementing timers, synchronizer switches, and intercepting physical hardware resources in a virtual system does not allow solving the problem one-to-one as on physical hardware; a lot depends on the specific vendor.
We conducted a test to study threading speed to assess how much virtualization can affect the speed of single-threaded tasks in 1C, including interface operations.
From the results obtained, the most important conclusion is not the numbers, but the fact that experience is still required to find in practice, and not theoretically, the optimal option for operating 1C for your specific load.
The effect of the virtualization layer is especially noticeable on very fast operations. information base 1C and this is logical. The shorter the operation time, the longer it is comparable to the latency time for servicing the virtualization layer.
In other words, if we perform one long surgery thousand seconds, then a lag of one tenth for virtualization maintenance will be a drop in the ocean and not noticeable. But if we perform ten thousand operations with each operation taking one tenth of a second, then service delays will be noticeable since they will be commensurate with the duration of the operation.
WHAT TO DO
There are two ways to solve the problem.
1st method. If you cannot achieve the desired performance with your virtualization settings, use physical hardware.
2nd method. Minimize virtualization lags by selecting settings that match the nature of the load. At the same time, you need to understand that virtualization is not 100% analogous to physical equipment and you need to compensate for the speed with more powerful physical equipment.
Some vendors provide increased speed through caching mechanisms built into the virtualization layer. However, the cache may be “broken” and then there will be a sharp drop in performance. Those. We must remember not only about the advantages of technology, but also about the disadvantages.
1. “Snapshots” should be turned off - they slow down. Moreover, the influence is far from obvious. For details see http://vkeygen.blogspot.ru/2011/10/snapshot.html
Microsoft Hyper-V
- when using Hyper-V servers with NUMA nodes 
VMware ESXi & vSphere
Collective use of virtual machines for load balancing
The problem lies in the operation of a vCenter component called DRS (Distributed Resource Scheduler), whose task is to balance the load of virtual machines on physical servers.When heavy loads appear in terms of processor power or RAM load, DRS migrates the virtual machine to another physical host that is least loaded at the moment; at the climax this process short-term problems arise with access to the resources of this VM.
NET
For ESXi 6.0 virtual servers with 1c server, do not use network interfaces of the WMXNET3 type, use only the e1000e type 
RAM
- Disable memory deduplication for EXSi - Transparent Page Sharing on the VMware ESXi host
If you want to disable this mechanism right now, then you need to do the following:
In older versions
After the patch and ESXi updates, the TPS mechanism can be enabled as follows (Advanced Settings in the Software section):
- Parameter Mem.ShareForceSalting(enable TPS at the entire ESXi host level). If the value is 0, then TPS is still running on the host, if 1, the mechanism is disabled.
- Parameter sched.mem.pshare.salt(set at the VM level) allows you to enable/disable TPS for individual virtual machines (for example, old Windows or Linux - you could enable it for them). When the ShareForceSalting parameter is set to 1, then for machines that need TPS in their Advanced Configuration, you need to set the same salt values. Without this, TPS does not work - accordingly, it is disabled.
CPU
— Enable maximum performance power supply 
— vSphere knows very well about and tries to place virtual machine kernels on those physical processors in whose memory the RAM virtual machine. But here pitfalls arise. Server manufacturers like to include NUMA emulation in the BIOS by default. That is, the server appears to the operating system as a NON-NUMA device, and vSphere cannot use its optimizations to manage this technology. The vSphere documentation recommends disabling this option in the BIOS; this allows vSphere to deal with the issue on its own.
DRIVER
— Install VMware Tools Guest Additions
The first thing you need to do after installing the guest operating system inside the virtual machine is to install software package– VMware Tools Guest Additions for VMware. These packages contain special drivers that provide more fast work guest operating system on virtual machine hardware.
Select Install VMware Tools from the virtual machine menu. Follow the instructions on your screen to complete the installation. If you are using a Windows guest OS, then you will see that this process is no different from installing other applications.
Checking VMware Tools.
- Select a host in vClient;
- Go to the tab Virtual Machines;
- Add a column "VMware Tools Status";
- Assess the status. OK->that means everything is fine, you don’t need to do anything. Not Running/Out of date - eliminated.
If VMware Tools is not running, you need to deal with the guest operating system. The reason may be an update to the Linux kernel or a disabled (by someone) VMware Tools service in Windows.
If VMware Tools are out of date, you need to update them from context menu vClient. Typically, this happens after installing updates on ESX/ESXi hosts. After this, you often need to update VMware Tools.
DISCS
— When using external storage
- Independent Persistent Mode of a vmdk disk is the most productive, since changes are made directly to the disk without being logged. But such a disk is not subject to snapshots and cannot be rolled back.
- When using iSCSI, it is recommended to configure jumbo frames (MTA=9000) on all interfaces and network equipment.
- MultiPathing - for most cases RoundRobin - OK. Fixed can give better performance, but that is after thoughtful planning and manual configuration of each host down to each LUN. MRU can be installed in an active-passive configuration if some paths disappear from time to time - so as not to jump back and forth.
What does abandoning virtualization look like in practice? Virtualization does not always slow things down significantly, but the nature of the load and the volume of data also matter.

I present my experimental project VM1C. VM1C is a virtual machine that allows you to compile and execute any procedures and functions, as well as entire modules, on the fly.
Essentially, this is the missing full-fledged Reflection feature in 1C, which is present on other platforms, for example on .NET, and allows you to do truly mind-blowing things there.
For those unfamiliar with Reflection: Wikipedia
Description of work
VM1C works without using any external components using only staffing capabilities 1C, does not depend on the platform and configuration. Can be added to the configuration either as processing or as a general module.
VM1C includes:
Let's look at each component separately
VM1C_IL_Compiler- its task is to convert the source text of a module or method into a set of short assembly instructions.
For example the following code
For n=1 For 100 Cycle n = n+1; EndCycle; Return n;
will be converted to a set of instructions
push 1 stloc 0 push 100 stloc 1 br ~IL_1 ~IL_2: ldloc 0 push 1 add stloc 0 ldloc 0 push 1 add stloc 0 ~IL_1: ldloc 0 ldloc 1 ble ~IL_2 ~IL_0: nop ldloc 0 retThis is done in order to
- speed up further code processing in real time. Since the compilation process itself takes a relatively long time
- provide the ability to create and perform procedures and functions in 1C Enterprise mode
Vm1C_IL_Compiler = Processing._VM1C_IL_Compiler.Create(); Module text = LoadCodeFromFile("Modules\WorkingwithProducts"); module = vm1C_IL_Compiler.CompileModule(Moduletext);
Once we have the intermediate code (IL code), we can execute it in the virtual machine.
Virtual machineVM1Callows, on the fly, using a JIT compiler, to compile a module from IL code back into understandable 1C code. The compiled code is optimized, cached for later reuse, and can be executed.
Vm1C_VM = Processing._VM1C_VM.Create(); vm1C_VM.AddModule("WorkwithProducts", module); parameters = New Array(); parameters.Add("00000453"); Result = vm1C_VM.CallMethod("WorkwithProducts", "GetPrice", parameters);
MethodInfo = vm1C_VM.GetCurrentMethodInfo(); parameters = methodInfo["Parameters"]; ...
get function code
ByteCode = methodInfo["ByteCode"];
change it, add parameters and call it again in a modified form, etc.
Conclusion
The project is now at the stage of a raw alpha version, so I’m only posting its description and demo video.
The purpose of this publication is to assess the need for this product, how useful it can be for developers, in cases where standard means is no longer enough to implement the most innovative ideas.
If anyone is interested this development, please be sure to let me know!
Demonstration of work
Sincerely,

Update: the publication was in drafts for a long time, because... Apart from academic interest, no practical application was immediately found this project. But recently I managed to use its capabilities in practice and it was decided to return the publication. Soon technologies from this project will be used in a new Code versions Inspector.
Thanks to the new full-fledged compiler, the Inspector will receive static analysis and, accordingly, a number of new features:
Checking that the condition is always True or False and that the function returns the same value. Checking not only the last unused values of variables, but also intermediate assignments, taking into account loops and branches. Code analysis in accordance with preprocessor instructions (On Server, On Client, etc.). Well, and much more.
1C-Bitrix: Virtual Machine" was developed directly for the needs of projects on 1C-Bitrix.
