[Queue-developers] performance issue notes

[Mike C. <da...@ix...>]

In comparing the performance of the latest CVS stuff vs 1.30.1, I've
noticed a significant change in speed.

I'm using as a simple test case a compile of zlib-1.1.3.

I'm doing:

time make CC=mygcc -j

For some base line numbers:

time make:  24.7 sec  (ok, it's only a P5-233)
time make -j: 24.8 sec
time make CC=mygcc:  43 sec (1.30.1)
time make CC=mygcc -j:  27.2 sec (1.30.1)
time make CC=mygcc:  44 sec (1.40.1)
time make CC=mygcc -j:  35 sec (1.40.1)

This is all with default settings in the now/profile.  Only one machine in
the system (I haven't started using nfs locking yet, so if I run 2
machines, they die pretty quickly with random file corruption, so I can't
tell how well it scales across two machines).

I am going to start profiling to see if I can see any major issues.  But I
was wondering if anyone else has noticed similar performance changes.
(geocrawler seems to be down at the moment).
