I spent more time testing this particular issue. I believe that what
appeared to be lost traffic is simply due to the shortened keepalives
and the load balancer favoring keepalive connections over new
connections. However, there still seems to be a link between gzip
settings and the number of open connections (keepalives).
gzip_disable "MSIE [1-6]\.(?!.*SV1)"
#gzip_buffers 64 4k;
#gzip_min_length 1100; #if it fits in one packet, no worries
I have confirmed that if any one of the three config lines at the bottom
(the ones that are commented out) are present, the number of open
connections drops from ~7600 to ~1300. Removing that line from the
config and reloading restores normal operation. Strange.
