I’m using nginx as a reverse proxy to my backends. I see there is a
huge discrepancy between upstream response time and request time.
X.X.X.X [15/Oct/2008:09:32:57 -0700] “GET /js/something.js HTTP/1.1”
upstream_response_time 0.005 request_time 105.026 90732578
It’s generally negligible. But sometimes its as high as 5 or more
seconds, and in some cases as high as the example above.
Any idea what’s happening? nginx is running on a dedicated server, and
has about 2000 active connections.
