Thanks for that document...
How do you make payload only 64 bytes? Is that include the TCP header
and HTTP header or not?
F5 is also use Linux 2.4 kernel, how could they get the new connection
/ per second count so high?
We are trying to twist the kernel code to see what can we do to make
the new connection number
go up. Anybody tried to tweak the kernel for improving the performance?
Also, what would limit the total number of connections? I tried to
add more memory and does not
seem help. May be some kernel parameter limiting it?
