We are conducting performance testing and I amd seeing very slow response times. I have adjusted the "delayed-ack-timeout" to 50 from 200 seconds and turned "OFF" Nagle. This has seemed to help tremendously but things are still off. What other variables can I adjust to improve performance? Has anyone had any similar issues before? I am running SSLM 3.1.(1) and CSM 4.1.(6) both Safe Harbor Releases. Bellow are some performace numbers gathered from Silk testing.</P><P></P><P>Web Server SSL: </P><P> 37.0 ms SSL handshake</P><P> 1.4 ms server busy time</P><P> 3.6 ms received time</P><P> </P><P>CSM SSL: </P><P> 9.4 ms SSL handshake</P><P> 6.8 ms server busy time</P><P> 62.0 ms received time</P><P></P><P>Let me know what you guys think</P><P>Thanks</P> Tue, 25 Jul 2006 22:50:41 GMT https://community.cisco.com/t5/application-networking/csm-sslm-performance-issues/m-p/505678#M9534 jim.papantonopoulos 2006-07-25T22:50:41Z Re: CSM SSLM Performance Issues https://community.cisco.com/t5/application-networking/csm-sslm-performance-issues/m-p/505679#M9535 <HTML><HEAD></HEAD><BODY><P>Is that for a single page download from one client ?</P><P>Or are you testing this under load - many clients ?</P><P>could you use bigger files and see if the response time is more equal ?</P><P>Be aware that the SSLM is designed to handle many simultaneous connections and may therefore look not as good as a server when testing with a single connection and small transfers.</P><P></P><P>Gilles.</P></BODY></HTML> Wed, 26 Jul 2006 07:16:08 GMT https://community.cisco.com/t5/application-networking/csm-sslm-performance-issues/m-p/505679#M9535 Gilles Dufour 2006-07-26T07:16:08Z Re: CSM SSLM Performance Issues https://community.cisco.com/t5/application-networking/csm-sslm-performance-issues/m-p/505680#M9536 <HTML><HEAD></HEAD><BODY><P>Yes single page from one client.
