The limitations on the number of users on a single PC-based Jabber server will be more related to the choice of OS (FreeBSD, Linux[flavor of the day], etc) than the PC hardware specifications. The number of simultaneous connected users will be limited how the OS handles select() for more than 1024 connections- in general, once you get above 1024 concurrent users, the select() logic will become a bottleneck, particularly on Linux 2.2 and earlier. The Commercial Jabber.Com version of the server does not have this limitation, and future releases of the Open Source server may also include a scalability fix to work around the limitations in select(). A limit on the total number of registered (not just concurrent) in the 'stock' jabber distribution is the spool directory structure. The user 'login.xml' files are stored in a single flat directory, as the total number of users grows, opening files in this directory will slow greatly. It appears that switching to xdb_sql or xdb_ldap does _not_ entirely cure this problem, as the spool files are still used for some operations.
