Re: CentOS 3 vs. CentOS 4 Memory Utilization

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



I said i moved away form Red Hat 2.4x kernels due to the memory issues. I use Red Hat 2.6x kernels now as they seems to behave properly in regards to swap. I have seen it way too many times with RH 2.4x kernels on many many machines.

I should have mentioned that every time I compare a 2.6 kernel with RHL 7.3 on this test:
hdparm -t /dev/hda

RHL is always faster. I was also running some other tests involving bonnie{,++} where RHL was still looking good, then Google interevened.

Known problem.

It was a year or so ago, maybe it's fixed.
