Improving the performance of service systems under VMware virtual machines

ImproveVMwareoperating performance method of service system under virtual machine

   due to the limited physical resources of the test environment, often the company will provide a relatively good configuration of the physical server let us install multiple virtual hosts in the server, if the physical server isLinuxsuch an operating system can useDockercontainer, if you are using thewind2008and Other services operating systems, some will choose to useVMSvirtual machines for some testers to usewind2008such as service operating system when host, and then installed in the host corresponding to the different types ofVMSThe virtual operating system is relatively easy, but the performance aspect is also a big problem, the following is aboutVMSvirtual software using some of the prior optimization configuration method recommendations, provide reference, can greatly improveVMwarethe operating speed of the virtual machine, the specific optimization configuration is as follows,

1 , upgrade CPU

CPU need to be able to cope with and handle multiple VM OS the computational tasks, of course faster CPU will provide a higher rate of operation

Description: Using virtual symmetric multi-processing (SMP) technology, you can assign processors and the number of cores per processor to virtual machines on any host system with at least two logical processors.

? optimize memory

Increase Memory Pair VM OS performance is inherently elevated, by increasing memory, we can allocate more memory to each virtual machine to prevent excessive data and resource exchange.

in the - the maximum amount of memory per virtual machine in a bit host is GB .

The total amount of memory allocated by all virtual machines running on a single host system is limited to only those on the host system RAM volume limits.

You can also configure settings to control memory Exchange.

to configure your memory preference settings, select Edit > Preference Items > Memory .

• Configuring Reserved Memory
  
  the reserved memory setting specifies the maximum amount of host RAM that Workstation Pro allows to reserve for all running virtual machines. Reserved memory is not allocated in advance.

• Configuring additional Memory settings
  
  additional memory settings are used to control how the memory manager in the host system can swap virtual machines out of physical RAM.

• Such as:

Additional Memory settings

Adjust all virtual machine memory to accommodate reserved host RAM

Selecting this option imposes the most restrictive limits on the number of virtual machines that can be run and the amount of memory in a given time. Under this setting,

Because the virtual machine runs completely in RAM, it may have the best performance.

Allow swapping of partial virtual machine memory

The host operating system can swap a modest amount of virtual machine memory to disk.

This setting can cause performance degradation if the virtual machine memory must be switched between RAM and disk.

Allow swapping of most virtual machine memory

The host operating system can swap virtual machine memory capacity to disk as much as necessary. This setting can cause performance degradation if the virtual machine memory must be switched between RAM and disk.

Optimize Disk

1, the use of SCSI virtual disk during installation is certainly better than the IDE virtual disk performance,

2, upgrading to a higher speed disk speed can greatly improve the performance of virtual machines.

3. timed defragmentation and compression of existing virtual disks
