My play toy just happens to be 8GB of memory.
My 8GB of Kingston memory arrived today for my Thinkpad T61p (two 4GB cards). I did realize a performance gain, and over the next few days I will assess whether multiple concurrent virtual machines perform faster and smoother. As you can see in the left-most image, my T61p now has 8GB installed with a Windows 7 64 bit host OS.
As far as a performance gain, the right-most AFTER image shows the improved performance using the Windows 7 performance metrics.
The right-most BEFORE image shows comparable performance before the Kingston memory installation.
As you may recall from my original Sep-2009 blog post
I have pursued several steps in getting ready for 64 bit Windows 7 and also extending the life of and improving the performance of my Thinkpad T61p. My principal objective has been to migrate my host OS and eventually all guest OSs to 64 bit, however in doing so I also wanted to speed up the hard drives while also adding additional memory to assist with the 64 bit host OS improved performance. To summarize the steps taken since Sep-2009:
Replace original T61p hard drives with faster Hitachi drives; both primary and Ultra-Bay drive. All VMs are on Ultra-Bay drive.
Consider which virtual machine management software I want to use with Windows 7 64 bit host OS. After a few problems, I realized that Microsoft had taken a significant step backwards with the Windows 7 version of Windows Virtual PC (WVP) support and I settled on using the new Windows 7 compatible version of VMWare Workstation; version 7.0. My biggest problem with VMWare Workstation was a problem in conducting an iPhone synchronization within a VMWare virtual machine; which ultimately was resolved as an iPhone data corruption problem
Replace my existing 4GB of memory with 8GB of faster Kingston memory. The obvious goal here was to provide memory beyond the 4GB limit for 32 bit OSs, so that Windows 7 64 bit can freely use all addressable memory, thus hopefully realizing faster and smoother virtual machine performance.
With the above steps now completely realized, here is a sampling of the end result; four concurrent executing virtual machines.....from left to right....1) My old Vista 32 bit Development VM, now converted from VPC 2007 to a VMWare VMDK VM...2) My new 64 bit Windows 7 Development VM; loaded with VS.NET 2010 Beta 2 and all the newly announced products from PDC Nov-2009....3) My 32 bit Windows 7 Administrative VM; containing Outlook, Quicken, etc....and lastly... 4) A small Windows XP image containing IE6 and Firefox 1.5, which I use for legacy testing. The 1st three VMs are assigned 2GB of memory each, while the Windows XP VM is assigned 256MB. Of course, the host OS is 64 bit Windows 7. Sure beats the COMPAQ arm stretcher portable I used to carry through airports in the mid to late 1980s.
Now....is this cool or what ?
