I got my fingers on a recent compaq proliant 1600 (640M/p3xeon700/7200rpm scsii) for a web server. Choice was Linux or BSD, and I decided to try FreeBSD :)This is how it looks like: bash-2.04# dmesg | grep da0 Mounting root from ufs:/dev/da0s1a da0 at sym1 bus 0 target 0 lun 0 da0: Fixed Direct Access SCSI-2 device da0: 80.000MB/s transfers (40.000MHz, offset 31, 16bit), Tagged Queueing Enabled da0: 17365MB (35565080 512 byte sectors: 255H 63S/T 2213C) bash-2.04# camcontrol negotiate da0 Current Parameters: (pass0:sym1:0:0:0): sync parameter: 10 (pass0:sym1:0:0:0): frequency: 40.000MHz (pass0:sym1:0:0:0): offset: 31 (pass0:sym1:0:0:0): bus width: 16 bits (pass0:sym1:0:0:0): disconnection is enabled (pass0:sym1:0:0:0): tagged queueing is enabled so, now, something from the daily life: bash-2.04# time tar xzf apache_1.3.19.tar.gz real 0m8.723s user 0m0.267s sys 0m0.216s I can't believe it should take 9 secs to decompress a 2 meg tarfile :( All linux boxes are faster - even the IDE based desktops... Any ideas what/how to tune ? Thx 4 any info in advance! ____________________________________________________ Javor Evstatiev Technical Consultant BLUE C New Economy Consulting & Incubation AG A-1070 Vienna, Neubaugasse 12-14/2/2 Office: +43 1 524 01 41 - 130 Mobile: +43 664 619 46 25 Fax: +43 1 524 01 42 ____________________________________________________ Visit our website http://www.blue-c.com to learn more about the New Economy Architects Can i dial 1-255-255-255255 and make every phone in the world ring? -- Tanuki To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
