delivers absolutely the best performance to applications using the BSD
sockets API. Please see www.openonload.org for more information.
EnterpriseOnload is a version of OpenOnload that includes an extended test
cycle, guaranteed support from Solarflare, bug fixes and a defined service
level agreement.

Documentation
=============
The Onload User Guide is available to customers with supported cards. You
can register and download a copy from: https://support.solarflare.com/.
You may also find the Solarstorm User Guide useful -- it is available from
the same place.
Quick start
===========
If deploying Onload from a tarball, then the following command will
build and install the Onload drivers into system directories (as root).
For instructions on other Onload installation packages (e.g. source RPM),
please refer to the Onload user guide.
/scripts/onload_install
You may need to reload the drivers if you have drivers loaded already:
onload_tool reload
Or to load the Onload and sfc drivers if none are loaded:
modprobe sfc
You may need to configure your ethernet interface with an IP address using
the standard tools. Please see the documentation that comes with your
Linux distribution for details.
To accelerate an application with the Onload user-level transport, simply
invoke the application on the command line as normal, prepended with
"onload".
ie. Instead of:
netperf -t TCP_RR -H myserver
do this:
onload netperf -t TCP_RR -H myserver
and tuned for best latency:
onload -p latency netperf -t TCP_RR -H myserver
Configuration and tuning
========================
Onload takes many configuration settings directly from the kernel stack.
In addition, there are a number of configuration and tuning options that
can be set via environment variables. See the Onload User Guide for
details.
You can get detailed descriptions of the configuration options in the
version of Onload that you are using by running the following command:
onload_stackdump doc
