We are currently using RedHat
6.0 with a Rainbow card and our program is using RPC and TCP, with some UDP for
our transmission between Solaris 8 and RedHat 6.0. We were able to
transmit 1000 transaction in 5-sec using this environment. I am trying to
find out what changed or what do I need to tweak to get the same rate on RedHat
7.3 or RedHat 8.0. With RedHat 7.3 or 8.0 it took 13-18 seconds to
transmit the same 1000 transactions. What has changed in these versions of
the Operating Systems. I can consistently get the numbers we need up to
RedHat 7.0. I thought it was the ethernet card, but it is the same one we
used in the 6.0 and 7.0 systems, 3com 3c905b. I even downloaded the driver
and installed it with not success in changing the numbers. We even tried
to tweak some of the TCP parameters with no great improvement, the most we could
shave off of the numbers was 2-seconds.
Or is there some documentation
I can read somewhere to find some answers.
