I want to disable TCP DELAYED ACK parameter on SUSE Linux Enterprise Server for some performance tuning operations.
I have used sysctl command but it does not list this parameter.
also in SUSE Knowledge Base Docs it is mentioned that "SET TCP DELAYED ACK = OFF" but not how to set it.
Can any one guide how to set it ? or any tool to set tcp parameters
I have asked this question on stackoverflow [here] earlier but as per their suggestion I am reposting it on serverfault.com

The only Linux kernel I know of which exposes Delayed ACK as a system-wide tunable is Red Hat MRG 2.0. You could use CentOS with the
kernel-rt
package which gets you the same thing for free.If you want to patch your own kernel here is a start.
The Novell knowledgebase article you have posted is over 10 years old and is for Novell NetWare, not Linux.
Everyone else in the world is using
TCP_QUICKACK
, you can too.
