Nginx stalled cache updating Locals ready to fuck no info needef

With 100 concurrent requests arriving all the time the server resources are quickly saturated, so we did another benchmark using only 10 concurrent requests doing 80 requests in total: $ ab -n 80 -c 10 -g Requests per second: 34.04 [#/sec] (mean) Time per request: 293.776 [ms] (mean) $ ab -n 80 -c 10 -g Requests per second: 26.50 [#/sec] (mean) Time per request: 377.311 [ms] (mean) Comparing the 6 milliseconds of a static page to on average 300 milliseconds of a PHP page tells us that serving PHP is 50 times heavier and an obvious goal for our optimization.

As always, the original Nginx source code can be downloaded from *) Bugfix: nginx could not be built –without-http_auth_basic_module; the bug had appeared in 1.0.3.

The Changelog from for version 1.0.4 is as follows: Changes with nginx 1.0.4 *) Change: now regular expressions case sensitivity in the “map” directive is given by prefixes “~” or “~*”. These Nginx for Windows packages are provided as is without any guarantees or warrantees. Download Nginx 1.0.4 for Windows (32-bit & 64-bit versions) here.

The PHP processor can in turn do more complex things, like query a database for information to be included in the response.

Finally when the PHP processor is done, the web server passes the result back to the browser that requested it.

Using Apache Bench we benchmarked the server by requesting a single CSS file thousands of times in succession, and varying the count of concurrent connections.

An example command that downloads a CSS file 8000 times using 100 concurrent connections is: The process for any static file is the same, so there is not much point in benchmarking many different static files.CSS, image, Java Script) and the web server only has to parse the request URI, fetch the file from the file system and send it away.The second and more complex case is when there is dynamic content: the web server parses the URI, notices it’s meant for a PHP file, passes the request via Fast CGI to the PHP processor.Visit Stack Exchange We have a situation where a site starts to serve a 502 Bad Gateway but doesn't seem to recover after the upstream servers rebound.The nginx server is setup to proxy/load balance requests for two upstream servers.In our case there are two distinct scenarios for response time.
