Response time for all services (web-proxy, web-server) is reasonable low (you almost don't notice any delay) c) Interactive programs (Mozilla, StarOffice, JEdit) are still quite usable. There is some delay when opening a file in SO (say, about 2-3 seconds), but that's fine d) Sometimes (but not really reproducable) I noticed a _big_ delay when connecting to the server using SSH (with "big", I mean 1 minute or so). I eventually get a connection, and then can work as normal. e) The server uses a single, but hyperthreaded CPU. Hyperthreading is enabled, and Linux shows both logical CPU's: root@setup:~ {529} $ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Xeon(TM) CPU 2.40GHz stepping : 7 cpu MHz : 2392.169 cache size : 512 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm bogomips : 4771.02 processor : 1 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Xeon(TM) CPU 2.40GHz stepping : 7 cpu MHz : 2392.169 cache size : 512 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm bogomips : 4771.02 But interrupt distribution seems a little bit strange: root@setup:~ {530} $ cat /proc/interrupts CPU0 CPU1 0: 6318080 0 IO-APIC-edge timer 1: 967 0 IO-APIC-edge keyboard 2: 0 0 XT-PIC cascade 4: 32477 0 IO-APIC-edge serial 5: 55629300 0 IO-APIC-level eth0 9: 85639064 0 IO-APIC-level acpi, ioc0, ioc1 11: 0 0 IO-APIC-level usb-ohci 15: 2 0 IO-APIC-edge ide1 NMI: 0 0 LOC: 6318529 6318527 ERR: 0 MIS: 0 With 2.4.21-rc6-ac1, interrupts where counted for both logical CPU's.
