On shell nodes, I find doing some simple tasks, like changing directories and listing files, is extremely slow. After some initial slowdown, it looks like it speeds up and subsequent actions are much faster, but initially they are very slow.

For example, doing the initial action for the first time:

$ cd ~/keep
$ ls
by_id  by_tag  home  README  share

took upwards of 60s or more.

Even though the 'by_id' directory didn't have any files in it, doing an initial 'ls' and 'cd' was also very slow.
