Should I have multiple replicas of free/busy public folder within an administrative group?

I am working with a customer who is having Outlook/Exchange performance issues.  Specifically, when they try to book conference rooms (selecting multiple conference room calendars and viewing free/busy to check availability), it hangs their Outlook client up sometimes several seconds, even minutes.  Other users reported slowness at times when just composing a message as well (hangs for a few seconds).   This is an exchange 2003 organization, one administrative group with 6 local servers (one of them is a dedicated public folder server) and 3600 users.  In reviewing Exchange Best Practices Analyzer reports, there is nothing major.  I did notice that there was an informational item indicating that there was just a single replica of the free/busy folder.  I have been reading conflicting information as to whether there should be multiple replicas within an adminstrative group.  Here is the link from the EXBPA report ( ).

Other documentation from MS I have found indicates that you should not have multiple replicas unless others are in a different physical location and with a slow link.  In this case, all servers are local and users on on the LAN (although there are some remote users who VPN in).

Should I create another replica on a server within a site?  I would be concerned then about replication lag, but if it will increase performance I would recommend it.  Also, the "show free/busy" details is the default setting for all the OUtlook users.
