With a recent CVS 2.9.5+ dated today, I did the following:

$ strace octave
....
octave:4> tic;toc

and found that it's searching the entire LOADPATH, every time.  These system calls are very slow.  Example:

access("/usr/local/share/octave/2.9.5+/m/control/system/clock.oct", R_OK) = -1 ENOENT (No such file or directory)

Many many unsuccessful probes.  I'd like to help clean the cache code if there's a problem with that.  This is what's slowing things down on the cluster.
