Likewise, we are running in VServer (www.linux-vserver.org) with no problems at all but our environment is currently much smaller - John On Tue, 2009-07-14 at 12:42 +1000, Luke Bigum wrote: > Hey Nick, > > We run Fedora DS inside Virtuozzo VEs (not VMWare) and don't have any capacity concerns, our environment sounds like a good tenth the size of yours though. Each VE (there's 2) has only half a GB of RAM and does about 100 connections a minute, however our LDAP database is very small, so the memory we've allocated is massive overkill.
