|
Should add mpm module(as below shows) at httpd.conf of apache 2.4.3 to increase the performance if I use mod_fcgid to run php scripts already?
# event MPM
# StartServers: initial number of server processes to start
# MinSpareThreads: minimum number of worker threads which are kept spare
# MaxSpareThreads: maximum number of worker threads which are kept spare
# ThreadsPerChild: constant number of worker threads in each server process
# MaxRequestWorkers: maximum number of worker threads
# MaxConnectionsPerChild: maximum number of connections a server process serves
# before terminating
<IfModule mpm_event_module>
StartServers 3
MinSpareThreads 75
MaxSpareThreads 250
ThreadsPerChild 25
MaxRequestWorkers 400
MaxConnectionsPerChild 0
</IfModule> |

Unless you are using linux / unix witht event mpm there is no use for that mpm settings 
For windows you want to use this
<IfModule mpm_winnt_module>
ThreadsPerChild 150
MaxRequestsPerChild 0
</IfModule>
Since there is only one child process on Windows the number of ThreadsPerChild is the number of concurrent connections.
Also it helps to use KeepAlive and of cause deflate. And right configured ETags also help to increase the performance. |

From Wikipedia
| Quote: | | An ETag or entity tag, is part of HTTP, the protocol for the World Wide Web. It is one of several mechanisms that HTTP provides for web cache validation, and which allows a client to make conditional requests. This allows caches to be more efficient, and saves bandwidth, as a web server does not need to send a full response if the content has not changed. |
So can reduce the number of requests to your server which increases the speed.
How I configured it (warning it is in german)
apache 2.4 docs

Does it mean to add "FileETag INode MTime Size" directive to .htaccess to enable etag?  |
