Fix Version/s: None
Alexey S has completed the round of testing with new PXC version and based on observation and experiment
current default values for following variables probably can be updated to the proposed optimal values.
fc_limit 16 100
send_window 4 10
user_send_window 2 4
It is not like if we leave them to current default we will not see performance gain but
now we are replicating faster and so for example: existing fc_limit of 16 is not enough and needs
to be upgraded. We of-course don't want to upgrade it to some really large value (like GR has 25000)
for SELECT latency issue that I am discussing through a blog post in coming day.
So if there is consensus we can proceed with this change.
I don't foresee any functional problem with this change but as a safety we will do it on branch
that QA can run through pquery-process and dev can run through mtr.
(We should able to fold it on by EOD).
