H A D | tcp_output.c | diff c39c4c6abb89d24454b63798ccbae12b538206a5 Wed Jun 03 12:10:42 CEST 2015 Wei Liu <wei.liu2@citrix.com> tcp: double default TSQ output bytes limit
Xen virtual network driver has higher latency than a physical NIC. Having only 128K as limit for TSQ introduced 30% regression in guest throughput.
This patch raises the limit to 256K. This reduces the regression to 8%. This buys us more time to work out a proper solution in the long run.
