When Crystal Enterprise (or BOE) run a report to be viewed, it keeps the run of the report in memory in the "Page Server" part of the software if it's an on-demand report or in the Output File Repository if it's a scheduled instance - and instance is loaded into the Page Server when the user requests to view it.  When a user views the report, individual pages are sent to the "Cache Server" part of the software to be rendered for viewing - each page is sent when the user requests it not when the view request for the report comes in.  I would check the settings on your Cache Server to see how large it is (try increasing it) and how long the pages can be in the cache.

 

Within the report, if you are using "Page N of M" or have more than one subreport on a page, that will also slow down the report.

 

On the machine where CE is installed, lack of RAM and/or disk space will cause speed issues (Crystal does a LOT of swapping to disk.)  You might also want to look at defragmenting the disk(s) on this machine to see if that helps.

 

Then there are issues of network latency or speed through the firewall.  Also, in IIS, try turning on compression as that might help.
