Server-Pool Management (MPM specific)

#

PidFile: The file in which the server should record its process

identification number when it starts.

#

Note that this is the default PidFile for most MPMs.

# PidFile "logs/httpd.pid"

#

Only one of the below sections will be relevant on your

installed httpd. Use "apachectl -l" to find out the

active mpm.

#

prefork MPM

StartServers: number of server processes to start

MinSpareServers: minimum number of server processes which are kept spare

MaxSpareServers: maximum number of server processes which are kept spare

MaxRequestWorkers: maximum number of server processes allowed to start

MaxConnectionsPerChild: maximum number of connections a server process serves

before terminating

StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxRequestWorkers 250 MaxConnectionsPerChild 0

worker 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

StartServers 3 MinSpareThreads 75 MaxSpareThreads 250 ThreadsPerChild 25 MaxRequestWorkers 400 MaxConnectionsPerChild 0

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

StartServers 3 MinSpareThreads 75 MaxSpareThreads 250 ThreadsPerChild 25 MaxRequestWorkers 400 MaxConnectionsPerChild 0

NetWare MPM

ThreadStackSize: Stack size allocated for each worker thread

StartThreads: Number of worker threads launched at server startup

MinSpareThreads: Minimum number of idle threads, to handle request spikes

MaxSpareThreads: Maximum number of idle threads

MaxThreads: Maximum number of worker threads alive at the same time

MaxConnectionsPerChild: Maximum number of connections a thread serves. It

is recommended that the default value of 0 be set

for this directive on NetWare. This will allow the

thread to continue to service requests indefinitely.

ThreadStackSize 65536 StartThreads 250 MinSpareThreads 25 MaxSpareThreads 250 MaxThreads 1000 MaxConnectionsPerChild 0

OS/2 MPM

StartServers: Number of server processes to maintain

MinSpareThreads: Minimum number of idle threads per process,

to handle request spikes

MaxSpareThreads: Maximum number of idle threads per process

MaxConnectionsPerChild: Maximum number of connections per server process

StartServers 2 MinSpareThreads 5 MaxSpareThreads 10 MaxConnectionsPerChild 0

WinNT MPM

ThreadsPerChild: constant number of worker threads in the server process

MaxConnectionsPerChild: maximum number of connections a server process serves

ThreadsPerChild 150 MaxConnectionsPerChild 0

The maximum number of free Kbytes that every allocator is allowed

to hold without calling free(). In threaded MPMs, every thread has its own

allocator. When not set, or when set to zero, the threshold will be set to

unlimited.

MaxMemFree 2048 MaxMemFree 100
