[users@httpd] Enhancement Request

Apache
MPM Workers



REQUEST:

Please change your worker parameter naming convention in regards to MAX.



Example:

Parameter1

MaxParameter1

Parameter2

MaxParameter2



Why?  I completely misunderstood the difference between ThreadLimit and ThreadsPerChild.  I have wasted over 8 hours researching the difference.



Try this out:

ThreadsPerChild    32

MaxThreadsPerChild  40



It is obvious what the relationship is between parameters with and without the prefix “max”.  Compare these ThreadLimit and ThreadsPerChild.  Following my proposed standard makes the relationship obvious.



Thanks



Lance

I agree that the naming can be surprising, but 
https://httpd.apache.org/docs/2.4/en/mod/mpm_common.html#threadlimit is, 
IMHO, clear enough.

A similar explanation should be added in 
https://httpd.apache.org/docs/2.4/en/mod/mpm_common.html#threadsperchild 
to help figure out the relationship between these 2 directives.
