For thoses interested on perfs, I finished setting up an ASUS P2L97-DS, 128MB SDRAM, 2 x PII 337Mhz (Oc'd 300). SCSI devs are : 2 x 2940 UW (+ 1 Internal chipset) Each 2940 chain have 1 x Quantum AtlasII 9Go and 2 x Ibm DGVS 9Go. (total : 6 x 9Go). The Ibm's are 10050 rpm, 18MB/s media rate. Using ccd's, 2 disks give a 33MB/s filesystem (best), and 27MB/s (average) reads. Writes seems to be far more slow. I tested 4 disks ccds and got a 52MB/s peak read. Unfortunetly, this raises the 'sys' activity to about 90%. ------ Problems encountered : - IDE CD attachment. (great problem since it's the only IDE device. The ATAPI code do not probe ide0:0, only ide0:1 if no disk found then the probing decide a way like : 'no disks ? so no Controller !!) - RC5 client : (FYI : 930 kk/s/processor). Using the SNAP-971012, I *NEVER* felt the load of the RC5 clients. Using the 971225, every time the RC5 clients are running, all disk activities are slowed (up to 10 time slower). Someone heard about a 'nicing' problem ? ------ Congratulations to all the SMP (and other FreeBSD-*) team(s)....
