The MMC 3.0 might not be the fastest console in the world so here are a few little tricks that might speed up the performance.

  1. Open Internet Explorer, select Internet Options and the Advanced tab.
  2. Remove the check mark from Check for publisher’s certificate revocation.

Another trick that might boost the performance when working with snap-ins in the MMC is to use the mmcperf.exe command found in .\Windows\System32\

  1. Open a command prompt
  2. Navigate to Windows\System32
  3. Type mmcperf.exe – you will notice that the mmc dll files are now being "GAC’d" which they for some unknown reason aren’t by default.

  4. Open a MMC and add a few snap-ins. You should be able to spot the difference in performance right away.
