using iostat and doing some basic file testing such as: time dd if=/dev/zero of=./tst bs=8192 count=8192 time dd if=./tst of=/dev/null bs=8192 count=8192
my write speed was about 13.5 meg a sec, and read was 13 meg a sec. I didn't explain my disk set up before, let me do that briefly. I have a SUN 1010 fiber disk array, with 16 18gig drives and 10 9gig drives. The file systems I am doing my tests on are a stripe of 4 18gig drives. I also did some tests with a SUN 711 attached to the same system which has a 36 gig drive in it, with that I get right under 20 meg/sec read and right (711 is attached with fast-wide scsi) I'm going to recompile 2.2.7 and see if I get any different results.. ----- Original Message ----- From: <[EMAIL PROTECTED]> To: "Justin Richards" <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]> Sent: Thursday, November 28, 2002 2:29 PM Subject: Re: [SAMBA] config/performance problem on solaris 8 > On Thu, Nov 28, 2002 at 02:24:16PM -0600, Justin Richards wrote: > > I have tried your advice, infact I removed everything but the necessary > > server information and still no difference. read speed still very good, > > write speed still way below par. > > Ok, now you have to do some work to profile the system and see > where the bottleneck may be.
