Improving Virtual PC performance by enabling disk cache

Just read this tip about improving Virtual PC performance of non windows images. Well I am not very impressed with the speed of my Gentoo image so I will test this pretty soon.

When you are running operating systems other than Windows NT / 2000 / XP / 2003 under Virtual PC you can gain a performance boost by enabling host side disk caching. This is not enabled by default as it is not architecturally correct behavior – but I have seen situations where it can result in a 25% speed improvement in disk I/O intensive applications. You can enable host disk caching by starting Virtual PC with the ‘-usehostdiskcache‘. This setting is then enabled globally on all virtual machines that you launch in that session.
