Title: Cognos 8 Performance ISAPI vs CGI
Post by: jguevin on 02 Nov 2006 08:43:30 AM
Has anyone out there done any testing or has implemented ISAPI instead of CGI for Cognos 8?  I was wondering if performance was better.  Cognos has a document  on the steps to change it over, but it does not say if things will speed up.

Thanks
Jeff

I always feel ISAPI is much better than CGI. In 1.1 cognos has mentioned that ISAPI is much better in performance than CGI. We have ISAPI in 1.1 and even in 8.

explain :
each *.cgi is opened when someone runs something in the portal (report/studio).
a regular Win OS can run only 256 processes at a time (after that it will crash).
changing to *.isapi gives you the ability to run 256 threads in one runs of isapi.
think of tcp/ip and the

Short for Internet Server API, ISAPI is an API for Microsoft's IIS (Internet Information Server) Web server. ISAPI enables programmers to develop Web-based applications that run much faster than conventional CGI programs because they're more tightly integrated with the Web server. In addition to IIS, several Web servers from companies other than Microsoft support ISAPI.
