I noticed a change in my BogoMIPS today. It seems related to building a kernel with IP masquerading. I have read the BogoMIPS mini-howto and the IP Masquerade mini-howto and still can't figure out why it is happening. System: HP OB800 Laptop Processor: Intel Pentium 166Mhz/MMX Kernel: 2.0.33 Here is how I figured it was due to IP Masquerading: [root@f2426bre /root]# cat /var/log/messages |grep -i bogo Jan 26 18:52:01 f2426bre kernel: Calibrating delay loop.. ok - 328.50 BogoMIPS Jan 26 19:20:15 f2426bre kernel: Calibrating delay loop.. ok - 328.50 BogoMIPS Jan 26 19:20:15 f2426bre kernel: Calibrating delay loop.. ok - 328.50 BogoMIPS Jan 26 22:47:46 f2426bre kernel: Calibrating delay loop.. ok - 246.58 BogoMIPS Jan 26 22:47:46 f2426bre kernel: Calibrating delay loop.. ok - 246.58 BogoMIPS Jan 26 22:57:16 f2426bre kernel: Calibrating delay loop.. ok - 246.58 BogoMIPS I had lost 82 BogoMIPS (25%) on Jan 26th. Checking my last kernel config date, I noticed that it was also Jan 26th. I rebooted with an old kernel, and sure enough back to full speed: Jan 31 10:59:12 f2426bre kernel: Calibrating delay loop.. ok - 328.50 BogoMIPS I also noticed that there were unresolved symbols with the module dependencies when I booted this old kernel. They were all related to the modules for the IP masquerading feature. I recompiled my kernel without IP masquerading and the BogoMIPS went back up to 328.50. The odd part was that the IP masquerading stuff was built as modules and they weren't even loaded. - brett | ||||||||||||
