32 Virtual PC performance vs Installed on 64 bit machine
in [Virtual PC]

From: Mark Love on 5 Mar 2010 07:23 Hi all, We have a 64 bit machine that for various reasons (compatibility) we may need to install a 32 bit os on. The alternative is to set up a VM on the machine. Is the performance of the VM likely to be significantly different to a 'native' 32 bit os installation? Thanks... -- Regards, Mark
From: Robert Comer on 5 Mar 2010 09:05 That's a very hard question to answer without knowing what you're going to run on it. Some things are faster in a VM than others. -- Bob Comer "Mark Love" <mlove(a)mastercontrol.com> wrote in message news:79DF5C60-E733-4756-BB51-DDF783F02421(a)microsoft.com... > Hi all, > We have a 64 bit machine that for various reasons (compatibility) we may > need to install a 32 bit os on.

From: Mark Love on 5 Mar 2010 10:11 Thanks for coming back Bob. They're development machines so will be running Visual Studio with some third-party libraries and probably an Oracle 10 instance for local development purposes. It's only the libraries and the Oracle 10 that are the problem here, otherwise we'd just run 64 bit anyway.

From: Robert Comer on 5 Mar 2010 10:22 A lot of disk access can be slower but you should be mostly okay. I'd test first before jumping in, I don't really know how well Oracle runs in a VM. If you have fast disks and you allocate a fixed size VHD it should be pretty close to real hardware. One problem though at the moment, networking between the host and guest has a bug in it right now and is extremely slow. There's no problem talking to other PC's from the guest, just not the host. The workaround for that is to use a dedicated NIC for the guest(s). -- Bob Comer "Mark Love" <mlove(a)mastercontrol.com> wrote in message news:74F57963-F27B-4A88-95D2-8BE052D7D01C(a)microsoft.com... > Thanks for coming back Bob.

I've used a two guest layout with VPC 2004 and 2007 for a while, one virtual machine running Oracle 9 and the other one Tomcat, Apache and Eclipse. This setup is slower than running the software directly on the host machine, but easier to manage. It is definitely slower than having your own dedicated Oracle server on another machine. Oracle works fine, even with limited memory. Don't expect a realistic response time from data warehouse applications with lots of data and huge result sets. If your IDE has to support a large development environment with extended compilation times, you might get frustrated. Regards, Andreas |
