Hi,
Would you please check what the results of this are with CPU specific
callwheels?
I'm doing some 10+ gig traffic testing on -HEAD with RSS enabled (on
ixgbe) and with this setup, the per-CPU TCP callwheel stuff is
enabled. But all the callwheels are now back on clock(0) and so is the
lock contention. :(
Thanks,
Hi,
Like stated in the manual page, callout_reset_curcpu/on() does not work
with MPSAFE callouts any more!
You need to use callout_init_{mtx,rm,rw} and remove the custom locking
inside the callback in the TCP stack to get it working like before!
Thank you!
