While I have never written libm-style libraries myself, I do have knowledge of both computers AND mathematics, and I do teach two university courses: Numerical Methods and Numerical Linear Algebra.

I would be happy to take on any steep learning curve, and make contributions, if only I were part of a group that would steer me in the right direction. Finally, Steve made a point that the way gcc multiplies complex numbers is wasteful in computational time. I have been bitten by this. I wrote some code that involved multiplying large numbers of complex numbers. I first wrote it using the complex C99 code. Then I rewrote it using double, writing out the complex multiplication long hand, and the program went twice as fast! (It involved multiplying numbers that were purely real or purely imaginary, so performing (x)*(I*y) by (x+0*I)*(0+y*I) really did slow it down.)

the idea is to return proper number of tcp connections (for both ipv4

Now = after applying my patch or after changing system? Which knobs were enabled? Now as in -current as against 8.x. But, that 2½ mins was wrong, sorry. I recalled 150s but actually checking, it's really 1:50 (100s). It occurred to me that was an oldish -current (r235127) so I updated to r236183 and the time dropped to 107s. Since this is an oldish P4, I tried a UP kernel and that reduced it to 96s. Your patch made no noticable change (ministat reported no difference with 95% confidence). The system is amd64 with no MK_* knobs defined. Then you should try to profile it - my script basically runs delete-old delete-old-libs for every knob (131 of them), and it hadn't taken more than 4 seconds even once. I've done some investigating and the problem is that xargs -n1 fork()/exec()s /bin/echo on each file (and there are 5538 files for me). Changing this to tr ' ' '\n' reduces make delete-old runtime to 1.75s - which is much nicer. I've checked a variety of other systems running 8.x 9.x and the 97s seems to be anomalously long so I'll do some more investigating. -- Peter Jeremy pgp23vtZvpadf.pgp Description: PGP signature
