Ok, this is going to make me sound like a newbie and that I have no idea what is going on.... What is a bogomip? -----Original Message----- From: juergen.braukmann@ruhr-west.de [mailto:juergen.braukmann@ruhr-west.de] Sent: Friday, May 12, 2000 4:20 PM To: SuSE Linux English Subject: Re: [SLE] bogomips issues in 2.2.15 kernel Alex Daniloff wrote:

Does it mean that kernel 2.2.15 was noticeably improved over 2.2.14 kernel? Thanks for any suggestions, Alex

Well, that limits my previous statement about bogo mips even to the same kernel level. Do you "feel" it's faster? I mean an improvement of factor 2 should be noticeable. I still state forget about bogo mips. Take a serious benchmark program.

Hello Juergen, I noticed some speed increase on my home linux system with 2.2.15 kernel and I didn't notice any difference on my work linux system with the same kernel. I think it is because my home SMP linux box is running Reiser FS which is generally faster than ext2. For my home system I patched 2.2.15 kernel with stable release of ReiserFS ver. 3.5.18. For my work linux system I left kernel 2.2.15 as it was with default ext2 FS. Regards, Alex On Fri, 12 May 2000, juergen.braukmann@ruhr-west.de wrote:
