Basically guys, this box is not exceeding an ide computer I have on = idea. I noticed the dual xeon to be slow. So I ran: dd if=3D/dev/urandom of=3D/dev/null bs=3D1m count=3D1024 on 2 servers, 1 is the top one and 1 is the xeon. Obviously the ide killed the scsi with dual cpu's running = hyperthreading, why? -SINGLE 2.4ghz p4 w/1gb ram and 80gig ide 1073741824 bytes transferred in 266.387823 secs (4030747 bytes/sec) 2.4ghz CPU: Intel(R) Pentium(R) 4 CPU 2.40GHz (2399.74-MHz 686-class CPU) Origin =3D "GenuineIntel" Id =3D 0xf27 Stepping =3D 7 =20 Features=3D0xbfebf9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR,PGE,MCA= ,CMOV ,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE> real memory =3D 1073676288 (1048512K bytes) avail memory =3D 1039519744 (1015156K bytes) ad0: 76319MB <WDC WD800JB-00DUA1> [155061/16/63] at ata0-master UDMA100 ----------------------- -dual 2.4ghz xeon each with hyperthreading, 2gb ram ddr, 73gb scsi hd. 1073741824 bytes transferred in 410.476271 secs (2615844 bytes/sec) CPU: Intel(R) Xeon(TM) CPU 2.40GHz (2395.92-MHz 686-class CPU) Origin =3D "GenuineIntel" Id =3D 0xf27 Stepping =3D 7 Features=3D0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PG= E,MCA ,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE> Hyperthreading: 2 logical CPUs real memory =3D 2146959360 (2096640K bytes) avail memory =3D 2085502976 (2036624K bytes) Programming 24 pins in IOAPIC #0 IOAPIC #0 intpin 2 -> irq 0 Programming 24 pins in IOAPIC #1 Programming 24 pins in IOAPIC #2 Programming 24 pins in IOAPIC #3 Programming 24 pins in IOAPIC #4 FreeBSD/SMP: Multiprocessor motherboard cpu0 (BSP): apic id: 0, version: 0x00050014, at 0xfee00000 cpu1 (AP): apic id: 6, version: 0x00050014, at 0xfee00000 cpu2 (AP): apic id: 1, version: 0x00050014, at 0xfee00000 cpu3 (AP): apic id: 7, version: 0x00050014, at 0xfee00000 io0 (APIC): apic id: 2, version: 0x00178020, at 0xfec00000 io1 (APIC): apic id: 3, version: 0x00178020, at 0xfec80000 io2 (APIC): apic id: 4, version: 0x00178020, at 0xfec80400 io3 (APIC): apic id: 5, version: 0x00178020, at 0xfec81000 io4 (APIC): apic id: 8, version: 0x00178020, at 0xfec81400 da0 at ahc0 bus 0 target 0 lun 0 da0: <SEAGATE ST373307LC 0004> Fixed Direct Access SCSI-3 device=20 da0: 160.000MB/s transfers (80.000MHz, offset 63, 16bit), Tagged = Queueing Enabled da0: 70007MB (143374744 512 byte sectors: 255H 63S/T 8924C) what could be causing this issue?
