Report instance view runs slow

Question

I am just starting to migrate Crystal reports into BOE XI R3, using the CMC to add the reports from the file system. With each new report, I create a recurring schedule and a run-now instance.
The first four reports performed well. The fifth seemed to hang the browser when viewed. I eventually found the process (View Latest Instance or view from History) would complete in about 15 minutes. At about 12 minutes, IE generates a message:
A script on this page is causing Internet Explorer to run slowly. If it continues to run, your computer may become unresponsive. Do you want to abort the script?
The CMC/browser status line shows it is trying to open crystalreportviewers / htmlbridge.jsp.
The instance takes about 1 minute to run in the CMC. The report uses about 60,000 records and produces about 4,500 pages.
In Crystal Enterprise 9, our current platform, the same instance is viewable in 2-3 seconds.
The first four reports migrated to XI3 run in less than a minute and are viewable in 5-6 seconds, have from 120 to 6,400 pages, and use the same dataset.
Not seeing any significant differences between the quicker and slower reports, I'm at a loss as to where BOE is failing. I'd appreciate some thoughts. Thanks!

Hello,
  If your looking for way to improve performance for the infoview please review 1292411 - How to Improve the performance of Infoview in XI R3.  Below is the resolution from that SAP note.  I hope this resolves your issue. 
Enable browser caching
Backup the exising web.xml <deploymant folder>\InfoViewApp\WEB-INF\web.xml  (where deployment folder is the location the applications that have been deployed in your environment)
Open the web.xml file and search for the text :
<init-param>
   <param-name>nocache</param-name>
   <param-value>true</param-value>
</init-param>
modify the line <param-value>true</param-value>  to <param-value>false</param-value>
save the file
restart your web application server
If you are using Secure Sockets Layer on Tomcat Application server then follow these instructions
Backup the exising context.xml <path to>\tomcat\conf\context.xml  (where path to is the location where tomcat is installed)
Open the context.xml file and add the text:
<Value className="org.apache.catalina.authenticator.FormAuthenticator" disableProxyCaching="false" />
save the file
restart Tomcat
