I recently upgraded an old Dell 8100 by putting in a Powerleap PL-P4/N processor adapter (socket 423 to socket 478) and upgrading the processor from a P4 1.33 MHz to a P4 2.6 GHz. Under Windows, there is a noticeable performance increase. In Linux however, performance is *horrible*--boot times are especially slow (~10 minutes). It looks like the kernel recognizes the processor, but it's still reporting ~1.33 MHz. $ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Pentium(R) 4 CPU 2.60GHz stepping : 9 cpu MHz : 1296.265 cache size : 512 KB physical id : 0 siblings : 1 core id : 0 cpu cores : 1 apicid : 0 initial apicid : 0 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 mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe up pebs bts cid xtpr bogomips : 2726.08 clflush size : 64 power management: Can anyone who knows more about this suggest something else to test/probe to help try and figure this out? -- Dylan Type faster.
