Is Virtual Machine Running Slow? The Complete Guide to Speeding Up Your Virtual Machines!

So let’s have a look at why our Virtual Machine Running Slow so that we do not make these mistakes while working on our machines.

Virtual Machine Running Slow

Virtual Machines became an integral part of our business-oriented computing. A virtual machine executes programs like an emulator of a computer.

It is a bit of software that permits you to run operating systems within. It can provide company adaptability, in that, any networking configurations or installed applications are going to be found out separately from the host computer, but rather will dwell within the software.

Every machine has advantages and disadvantages, and one of the disadvantages of virtual machines is that they run slow. 

Virtual Machines are slower because we are running them on slow hypervisors. They might be running slow because we assign too much memory to the virtual machine and starve the host operating system so it doesn’t have enough memory to operate efficiently by increasing the amount of memory reserved to run virtual machines.

There can be a number of reasons leading to the slow response of virtual machines:

  • Real Machines are more efficient than virtual machines because virtual machines access the hardware indirectly. Running software on top of the host operating system means that it will have to request access to the hardware from the host. That will slow the usability.
  • When several virtual machines are running on the same host, performance may be hindered if the computer it’s running on lacks sufficient power. Virtual machines still use the resources of your host machine. The efficiency of the virtual machine depends on the host. The more powerful the host, the more quickly the virtual machine is going to run.
  • A virtual machine can be infected with the weaknesses of the host machine. As an example, process isolation is a feature usually employed by operating systems. However, there are bugs that violate it. A regular computer devoid of virtual machines would then only be affected. But, a computer with a number of virtual machines would then infect each of those “machines” as well.

There are some ways to speed up your virtual machines:

1. Defragmented host operating system

  • This includes the System Disk (the disk your OS boots off of) also because the Disk that holds your Virtual hard disc File.
  • For a fast fix, use a single-file defragmenter like Contig from SysInternals. With the Virtual Machine pack up, run Contig -a to research file fragmentation and run without -a to defragment the file.

2. Run fewer applications

  • People complain about virtual machine performance but they’re actually running outlooks. That 200+megs might be better employed by the system. Consider checking your email on a schedule, or using Outlook Web Access while you’re employed on your VM.
  • If you’ve got 2 GIG or more of memory, consider running your Host OS without a Paging File. This does not mean you get to stay 50 applications, plus Outlook running all directly, but it does take the pressure off your Host OS’s disk, and you would possibly find things run considerably snappier.

3. Run the VM on a separate spindle

  • We can try and use a 7200RPM or 10000RPM drive for your VM disk.
  • Use USB2 or ESATA or Firewire
  • If you’re using USB2, confirm the Eternal disk drive is on its own USB root hub, all alone. Don’t share it together with your keyboard, mouse, or webcam.

4. Optimize your VM for your current task

  • Invictus Virtual Machine Optimizer is highly recommended for this. It’s inexpensive if you see the value sometimes. Consider getting a site license and truly do the maths at what proportion of time it will save your company when you’re trying to convince your boss. WE can run it over lunch on a VM and advance. yoIu’ll also do tons of the work manually if you have got the time using tools like XPLite and CrapCleaner (although less so with CrapCleaner if the box is already fresh).
  • Remove any application that’s not needed.
  • Shut down every service you’ll possibly escape with.

5. Enable Hardware assisted virtualization

  • If you have this on your computer, turn it on. There’s some concern about really sophisticated Trojans which will use this technology for evil, except for me, it’s all good because it speeds most Guest Operating Systems (especially non-Microsoft ones) up quite a bit.

6. Give your Virtual machine less memory

  • I’ve found that 512 megs is simply about the perfect amount of memory for 90% of your Virtual Machines. Don’t bother trying to offer them 1024 megs, it’s just not well worth the pressure it’ll place on the Host OS.

7. Custom windows install for virtual machines

  • Rather than getting to all the trouble to get rid of things, why not create a Windows installation which will be shared across your organization that does not include the crap before time. There is a Windows Installation Customizer called nLite that allows you to prepare Windows installations in order that they never include the things you do not want. 

8. Guest OS Defragmented

  • This free Disk Defragmenter runs therein “Text Mode” place before Windows really starts up. This enables it to urge files that do not always get defragmented.

9. Squish Virtual Machine disk drive

  • Exploit Invictus does this, but you’ll also zero out the free space on your VM disk drive with the Virtual PC Precompactor that comes with Virtual PC when hosting Windows, and there are Linux options for shrinking VM hard drives also.

10. Do Not Remote desktop or VNC

  • If you’re remoting into a machine where THAT machine is running a VM, note that to the Remote Desktop protocol (and VNC) the VM just seems like an enormous square bitmap that’s constantly changing. That guarantees you slow performance. If you’ll, instead, Remote Desktop into the Virtual Machine.

The above-written ways will help you.

So, the most reason a corporation would use a virtual machine is that they have to run separate operating systems on an equivalent computer. This will be for a variety of reasons, including if the present system isn’t sufficient for the requirements of the company’s goals.

A knowledgeable and tenured IT firm can help a corporation navigate the terrain of selecting the proper virtual machine to suit business demands. an honest IT firm also can aid in ensuring the system runs smoothly and efficiently, while constantly monitoring for performance and IT security. Always check small details before making a purchase and check what aspects of the machine can make it slower than usual.


How can we speed up our virtual machine?

We should enable our VIA VT, AMD-V, or Intel VT-x. The antivirus should ignore the VM’s disk images. These are some ways of speeding up your virtual machines.

How much slower is a virtual machine?

A virtual machine is much slower than a native system that can be from a range of 5 to 100%. 

How much RAM do we need for a virtual machine?

The Quick Create wizard assigns a default RAM of 2GB which is not enough for good performance. So a RAM of 4GB is used.
