The Institutional Repository, [EMAIL PROTECTED] installation is implemented 
using 
Fedora Core 4 Linux, Apache Tomcat 5.5.17, Apache Ant 1.6.5, J2EE 1.4 SDK
Java platform, Postgres SQL 8.1.3, and DSpace Version 1.3.2. 
This is installed on a machine with a configuration as follows : 
P4 @ 2.4 GHz, 256 MB RAM, 40GB HDD
 
There are currently 182 records in the IR. 
I have taken a backup of 
(1) asseststore  from /dspace  using the command tar -cvf assetstore.tar
assetstore/
      Size = 244 MB   
(2) database from /dspace using the command /usr/local/pgsql/bin/pg_dump
dspace > era-data 
      Size = 1.56 MB 
(3) dspace.cfg file from /dspace/config 
This I gather is enough to restore DSpace to its current state in case of a
crash.
 
DSpace scalability depends on hardware & storage 
-- no of concurrent users, amount of storage large objects etc. 
 
I am curious to know as to what would be the maximum number of records that
I would be able to handle on this machine ? how many concurrent users doing
search, upload are handled comfortably? Before what size of Database would I
need to upgrade the machine ? 
 
Thanking you
