Dear Sirs. Since the first occurence of the dirprefs discussion I got aware of a performance boost of all of our server systems. One machine, 2GB ECC RAM, 2x 866 PIII CPUs, TYAN Thunder 2500 main PCB and a AMI Enterprise 1600 RAID controller with 250GB RAID level 5 array compiled a whole world within 50 minutes (I use make -j 4 due the fact higher levels won't work and resulted in errors). After the code include of dirpref the system took only 40 minutes and this boost was detecteable on all of our systems. Today I did the last cvsupdate and compile a world and I was wondering why the system was really early ready with its job! Now a complete compilation of world take 30 minutes. This performance improofment has been seen on all of our server systems. Our scientists aproofed me that the calculation speed of several Linux software (Fortran, compiled with Lahey F95 V5.5 under Linuxulator) has slight improofments, I think this results in SSE enabled. Well, I don't want to celebrate a great festival, maybe my performance improofments around here results in a better configuration or a new mechanism of FBSD to work around worse administrators ... ;-) But I think this is something I should spread out into the world. While WindowsXP has been introduced and a lot more of our system resources went down the stream for more coloured pictures and more brain damaged stuff - but I see on the other side that elaborating in more efficient algorithms could have a much better 'impact' than 'verything new' for this MCDonalds-damaged, fast food world.
