connection initialization...tuning initcwnd

Hi,   I've been reading several posts by Jason Rahm. I'm wondering if you can help me or anyone with experience setting tcp settings on F5. I have some questions around tcp initialization costs....

You're welcome.

 

What about the client side network, is that reliable?

 

Also, what OS are the internal servers running? Because of this post I've been reading up on ICWS and IRWS settings for those and may be able to offer some advice there too if they are Linux based.

 

A 404 doesn't mean a persistent connection is closed and a new one established. The browser will close connections if it doesn't need them - I'm not sure if this can be controlled. The server (the F5 in this case) will also close unused connections after the relevant idle timeout period has expired. There's no specific HTTP related timeout so whatever the TCP idle-timeout value (default 300s/5mins) is will be used in most cases. There are exceptions depending on your configuration.
