Hi,
My server is running with Slackware 8.0 and kernel 2.4.18. I got a Pentium with a U160 SCSI Controller ( Tekram DC-390U3W ) / 3COM 3C905C and 128 MB RAM.
Compilation ran ok but I got some general performance problems. I have one client connected to this machine through samba system. At the beginning I directly looked at my network system and I changed a lot of TCP/IP parameters but my client cannot write more than 200 - 220 ko/s ( client 10Mps on this server 100Mbps ). My client can well download at ± 950 ko/s. This is all running fine but write sequence takes a while and I think that I normally could have upload with 650-700 ko/s.
So I am now looking at my SCSI interface. Maybe problem comes from there or eventually my Reiserfs config.
I compiled the kernel without applying patch-2.4.18.gz.
So my questions are the following : - do I have to apply this patch ??? - I took driver "SYM53C8XX Version 2 SCSI support". Is that the right one ( is that stable enough ??? ) or do I have to take another one ??? - do you see something wrong in the result of my dmesg command that can degrade write process ...
Thanks vincent
