Hi,

Some of them may be read google's article about tuning TCP parameters
[1].  I convert most of TCP timers to sysctls [2] and we are using this
patch for few months.  We tuned net.inet.tcp.rtobase and
net.inet.tcp.syncache.rexmttime and it gives good results (especially in
conjunction with cc_htcp(4)).

Is there any suggestions how to make patch better and commit it?
