First thing I personally look at when VMs are slower is disk slowdowns. It's always been the bottleneck on my machines. Writing to a massive file on the host's file system is going to incur overhead and slowdown. Having a separate drive available that can be directly accessed by the VM helps. Using solid state drives has also dramatically improved performance for me; it negated the performance hit. -- Gerard -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
