High network latency between domUs on SLES 11 SP1 Xen host
This document (7009790) is provided subject to the disclaimer at the end of this document.
options netbk tasklets=0 bind=0
Adding this line to the file and changing EITHER tasklets OR bind to 1 (from zero) causes the latency to be returned to normal. The default setting is in place because the benefit, better overall scheduling behavior of the dom0, outweighs the penalty reported initially.
Modifying kernel and driver settings should be done after thoroughly understanding the settings and verifying the benefits compared to trade-offs. While this option is configurable it is recommended to use the defaults as implemented.
