My interest in squid began few weeks ago when our manager thought it
would be nice if we had a proxy-cache. I loved the program and started
reading the code last week. Liked it a lot, and would like to read more
about how the development is going and the ideas that you guys have.
Thanks!
I also made a tiny little patch yesterday, and wanted to discuss the
performance issues of it. The problem was that it was hard to guess the
exact size to put in maximum_object_size. We would like to cache big
files from certain sites (like windowsupdate) and let a small default
for the others. Well, what I did (or tryed to do) was mimic the
reply-body-max-size option thus adding acl to the maximum-object-size.
Good idea.
If done correctly it should mainly have an effect on performance when
used.
What I want to do now is profile it and see if putting acls into that
option is a overkill. Reading the list archives I saw two main options,
gprof and a patch in squid to enable profiling and view the results in
the cachemgr. Since the later is not at the code I wander if patching
the squid for profiling is really the best option...
I'd say profiling this is overkill..
Problem with gprof is the sampling inaccuracy. Most function calls in
Squid is very short in time making the statistical error in run-time
measurements significant. But if you are aware of these limitations of
gprof then it's a valueable tool.
The performance qounters for Squid is an attemp in adding mor accurate
run-time measurements.
