"much slower"? We have a network license for Stata here, where the entire
wstata executable and all ado files are loaded across a network (via
Samba) and there have been no complaints about the speed of loading.

My understanding is that an ado file is loaded once when first referenced
in any Stata session, and is re-excuted (if necessary) from memory. So I
wouldn't expect any speed difference beyond a small fixed overhead (a
fraction of a second) for each Stata run. In a brief test here that was
confirmed. Am I missing something? Can you give an example of an ado file
that would be affected in a noticable way?
