[ome-users] import is slow

[Ilya Goldberg]

That is somewhat slow, but not sure what to suggest.  Fast computers  
and networks help :)  Multi-core computers help a lot.  The image  
server (OMEIS) benefits from plenty of RAM, and under-performs on OS  
X.  Distributing the various core components (database, web server,  
image server) among different computers (or cores) makes the biggest  
performance difference.  Poor network bandwidth to OMEIS will make  
almost everything very slow.

Also, big chunks of OME are compiled and loaded every time you launch  
the perl interpreter from the command line, but these things are pre- 
compiled and pre-loaded in Apache/mod-perl.  In other words, the Web  
UI may be noticeably faster on "small" jobs.
