O$4 vs O$3 performance

Hi Mary,

>server is a G5, 1.6GHz with 1.5GB memory

According to this

  http://www.datamemorysystems.com/_apple_info/Apple_G5_1.6GHz_Memory_1188.asp

and confirmed in the MacTracker app, that machine should have DIMMs 
installed in matched pairs, so having 1.5gigs is suspect.  The 
mismatching works but has a performance penalty.

If it was me, I'd go get four matched 1gig DIMMs for $150 and max out 
the server RAM.  That'd make them happy while you investigate your 
code for bottlenecks.  As far as I know there's no significant 
performance penalty built into Studio 4.x compared to 3.x.  I can't 
speak to ODB issues, haven't used it.  But faster disks and more RAM 
always help.  A two year old iMac would out-perform this G5 with a 
faster processor and a 3gig ATA bus vs the 1.5gig bus in the G5.
