Date: 13 Oct 1993 19:30:27 GMT Organization: Technical University of Berlin, Germany Lines: 21 Message-ID: <29hl0j$p3q@news.cs.tu-berlin.de> NNTP-Posting-Host: troll.cs.tu-berlin.de Mime-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: 8bit HI! Having run some tests with bonnie and iozone I was rather disappointed getting only about 250k/s filesystem performance with an 1GB Fujitsu SCSI-2 drive and Adaptec 1742A EISA (!). I would really like to learn more about tuning system performance... Perhaps some guru could post an easy description on the possibilities you have to get most out of your hardware. BTW reading rather often about people reporting Ethernet performances (ttcp) above 1000k/s with SMC 8013 cards I would also like to hear something about the relevant kernel parameters for network performance. -- ------------------------------------------------------------------------------- Lars Grupe UID lunde <lunde@cs.tu-berlin.de> Technische Universitaet Berlin -------------------------------------------------------------------------------
