Hello,
Recently, I had to update my VMware disk running Windows 7 as coming Windows 10 is not partially supported in my current VMware 6.5-7 VM. However, I am VMware Player user, no VM upgrading options supplied. So, I downloaded VMware vCenter Converter to convert my old VM to the newest one, and it happily converted to the most current version, 11.0 VM.
However, I found the upgraded machine is really sluggish and have intensive disk access (always disk access is on) to make my virtual machine very slow. Here is all what I tried.
- Disabling "Enable write cache".
- Reinstalling (installation and new installation) of VMware Tools.
- Adding the following settings to my vmxfile:
MemTrimRate= "0"
mainmem.backing = "swap"
sched.mem.pshare.enable= "FALSE"
prefvmx.useRecommendedLockedMemSize = "TRUE"
Unfortunately, these tweaks did not help.
The disk is not preallocated, and set as a single file (approx. 69 GB out of 80 GB). Defragmentation and Compaction have not been tried as it will take so long time (and I think these are complete when VMhas been converted). I used separated.vmdkfiles with approx. 2 GB, and suppose disk performance will improve by using split disk style.
Of course, I had no problem when I run this VM with 6.5-7 configuration.
Any ideas, suggestions and comments to improve disk performance of my VM? Thanks.
Here's a summary for host and guest operating systems.
- Host operating system: Linux (Ubuntu 14.04 64-bit)
- Host spec: CPU = AMD Phenom II X6 1090T, memory 16GB, disk 1 TB (for system) and 1.5 TB (for data)
VM is stored in data disk. - Guest operating system: Windows 7 (32 bit)
- Version of VMware Player: 7.1.2 build-2780323
- Host disk usage: 957 GB used out of 1.4 TB (74 % used)
