Need some input for an article...

[Lars Eilebrecht <La...@unix-ag.org>]

Hi,

I'm currently writing an article about the Apache 1.3 release for a
german unix mag...

When writing about performance I was wondering if Dean's 7-25%-patch
will make it into 1.3.0? In other words, when talking about a performance
increase of XX%, what will 'XX' actually be? :)
  
What about the mmap_static module? This won't be in 1.3.0, won't it?


ciao...

Incidentally, has anybody tried my mmap_cache module that I announced
some time ago?
http://www.atm.cs.ndsu.nodak.edu/~tatarino/apache

I know that it's not ready for wide use yet (no docs, etc) but it's pretty 
robust and unlike Dean's module it caches mappings dynamically. As a result,
on a small site (say < 10,000 files) it may be fine to cache all files
(except perhaps the tiniest ones, < 1k).

As for speed up, it might be upto 30% on a single file (zb with infinite
keepalive) but will probably be 5-10% on a set of files (log) with limited
keepalive (say, 5 requests/ka connection; I modified zb to support that)

Waiting for feedback!

thanks,
igor

The patch is in there already but I'm having troubles right now supporting
mod_include's bizarre habits with subprocess_env.  If I can't work them
out soon the patch may have to be partially removed.  As it is currently,
mod_include is broken for some sites, specifically sites which use
<!--#set --> in #include virtual files and expect the results to be
available in the parent.

I don't mind either way.  It was mostly a proof of concept...

There have been so many changes... and performance changes so much from
environment to environment... 10-50% would be fair in some cases.  In some
it is more.  Some less.

I'm hoping to get a chance to try it in one environment soon...

Who knows what will happen.  Unlikely, but anything is possible.
