what limits connections to Redhat servers?
Hey guys,
We have two server environments that are acting different however they are different OS's... Ubuntu vs Redhat
We have an Ubuntu environment that is able to maintain about 450 connections/second until about 120,000 connections. In our Redhat environment we are not able to match this or even come close. Both environments are almost identical hardware and are base OS installs.
Can you guys give me some redhat kernel parameters that are possible culprits for throttling connections? It is especially noticeable once you get above 90k connections on the Redhat servers.
Thanks,
Shaun

pbuilder-dist-simple
PBUILDER-DIST-SIMPLE(1) General Commands Manual PBUILDER-DIST-SIMPLE(1)
NAME
pbuilder-dist-simple - simple multi-release pbuilder wrapper
SYNOPSIS
pbuilder-<dist> operation [...]
DESCRIPTION
pbuilder-dist-simple is a wrapper that makes it easy to use pbuilder with chroots for many different Ubuntu distributions. If you need
more features than pbuilder-dist-simple provides, have a look at pbuilder-dist(1).
USAGE
Create one symlink to pbuilder-dist-simple for each distribution for which you want a build environment, naming them like "pbuilder-lucid",
"pbuilder-natty", etc.
Replace operation with the action you want pbuilder-dist-simple to do (create, update, build, clean, login or execute).
EXAMPLES
pbuilder-natty create
Creates a pbuilder environment for Ubuntu Natty.
pbuilder-lucid update
Updates an existing Ubuntu Lucid environment.
pbuilder-lucid build ./sample_1.0-0ubuntu1.dsc
Builds the specified package on an already existing Ubuntu Lucid environment.
FILES
By default, pbuilder-dist-simple will store all the files it generates in ~/pbuilder/. This can be changed by modifying the BASE_DIR value
on the top of the script to any other directory you want. If the directory doesn't exit, it will be created at runtime.
SEE ALSO
pbuilder(1), pbuilderrc(5), pbuilder-dist(1)
AUTHORS
pbuilder-dist was originally written by Jamin W. Collins <jcollins@asgardsrealm.net> and Jordan Mantha <mantha@ubuntu.com>, and this man-
page by Siegfried-A. Gevatter <rainct@ubuntu.com>.
