Howmany concurrent users are supported by network server

[Manjula G Kutty]

Hi,

I would like to know an estimate of howmany concurrent users are 
supported by derby network server. I know its hardware dependent, but 
for instance assuming a Windows box w/ 2Gb memory, single CPU, single 
7200rpm IDE drive.. Each user will be doing insert, delete, update and 
select.

Thanks
Manjula
