I've known about this (nginx getting slower over time) but not had time to
investigate thoroughly. I think its an nginx-specific issue; it may be to
do with the fact that we're running in the special "non-forking” mode
(master_process off), or not.
One interesting point here is the Nginx doesn’t start at the expected
performance level (approx 5,500 transactions), it starts at approx 1,300 and
then slows down.
How did you come to that conclusion? Performance seems slower after
each transaction. Your first batch contains 27+k transactions. It's
reasonable to assume that the first 10 in the batch were completed
faster than the last 10.
