Dominos 6.5.1 Web Server Performance Issue on Windows 2003

We recently ported one of our databases from Dominos 6.5.1 on Windows 2000 to Dominos 6.5.1 on Windows 2003. The servers are similar in configuration.

The application performs as it had on Win 2K, if we access it via a browser on the Windows 2003 server itself. However, the pages download very slowly, if we access the same content from a client PC’s browser.

We know that the Win 2003 server has no general network / TCP-IP issues. Every other aspects of the network communication perform well. Also, both the old and the new server are on the same network and are being accessed by the same client machines.

Any ideas? We have a hunch on what could be causing this…

  1. Does Dominos 6.5.1 rely on HTTP.SYS of Windows 2003 for HTTP communication? If so, does Dominos do its own caching of network packets? Is there a parameter we can set in notes.ini to control this?

  2. Do any of the programming features of Dominos 6.5.1 cause an implicit/explicit flush on network packets (similar to Response.Flush() in ASP or echo “$i
    \n”; in PHP)? Is there a parameter in notes.ini that would allow us to turn it off?

Thank you.

there is a compression that 6.5.1 does with http data. There is a notes ini setting that may help you by turning it off. iNotes_wa_GZIP_Disable=1
