After installing 1910 build I have noticed that when running windows (640Mb RAM) and Solaris 6/06 (256Mb RAM) Parallels total allocation (896 MB), Windows runs very sloooow. My hardware configuration is 2Gb RAM, 17" MBP, 2.1Ghz, 120G HD, Now there was nothing else running on Mac OS. Solaris was sitting idle (usually I build something in parallel but while I was watching I did avoid running and building anything on Solaris) While windows I was trying to import the same data from file (using my application) to MS SQL express. Not to give you idea. When running windows alone I can import this data in <5 min. Doing the exact same thing on windows while running Solaris in parallel to Windows It took 45 min !!!!!!!. (first Database was totally cleaned each time, then the same file imported). I even noticed this while I start shutting down Solaris windows started working much faster. I know that there was nothing running under Solaris. Doing top under Solaris was not showing anything running high. Looking @ Activity Monitor under Mac was showing about 6-10% CPU for Solaris. Windows on the other hand was running high in both cases. Also as reported before the host only networking is broken under Solaris 10 6/06 (even using the latest vmtools.iso). It can't get IP from Parallels internal DHCP. Works ok with External DHCP. But when I am on the train I need to use host only networking. Anyone is seeing this?
Be sure to give Parallels at least 10% more than the total amount of RAM assigned to all the VM's you intend to run simultaneously. (I've seen other notes in the forum that suggest 20% to 30% more would be better.) So, in your case, you should give Parallels at least 986MB and, possibly, as much as 1164MB.
