There’s nothing worse (OK there is) than working on a fully populated 6513 and you type show run and hit enter. Hurry up and wait for the switch to parse the config then display it to you. In digging around and looking for a solution to logging to a usb drive, I found an great command;

parser config cache interface |
What does it do? Loads the config into a cache. So what you say? Until a change is made, the switch will present you the config from cache instead of parsing it each time. No more waiting! Once you make a change, it will need to rebuild that cache again. Once you enable it, you will need to show run to build the cache, but subsequent show runs will be significantly quicker. Works on both routers and switches.
PS- There is another parser command that is useful –

parser config partition |
It works just like the section sub-command (from show run).
