I tried it by comparing the same VM with and without that setting. Here is what I found:
With "Use Host I/O Cache" disabled, booting took 40 seconds. With "Use Host I/O Cache" enabled, booting took 12 seconds. With "Use Host I/O Cache" disabled, doing a mini update took a few minutes. With "Use Host I/O Cache" enabled, doing a mini update occurred nearly instantaneously. I'm convinced. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/947664 Title: Unpacking linux-headers unbelievably slow in Lubuntu Precise (Beta 1) To manage notifications about this bug go to: https://bugs.launchpad.net/dpkg/+bug/947664/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
