Yes, 32-bit XP isn't so slow on my fast machine. But I've given 64-bit Win7 1.6 GB of RAM and it still crawls. A developer I work with recently acquired a brand new super-fast machine for his build farm and stuffed it with 8 GB fast RAM and virtual 64-bit Win 7 running on VMWare still crawled when given 7 GB RAM. Now we could both have goofed up our set-ups, but neither of us were happy campers. However, it should be understood that at least with Virtual Box, the RAM allocated to the virtual machine is only a minimum value. The virtual machine will still use more memory if it isn't in use by the host system. Virtual machines will never be as fast as running on bare metal. I suspect the difference just isn't as noticeable when running Ubuntu on a virtual machine because the Linux kernel isn't nearly as greedy for system resources as the Win7 64-bit kernel. -- Universal Interoperability Council <http:www.universal-interop-council.org> _______________________________________________ Blinux-list mailing list Blinux-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/blinux-list
