There is a discussion about the 2.4.21rc kernels on the SE Linux
Machines running 2.4.21rc kernels seem to have a kernel memory leak
makes them unusably slow. Opinion is divided on whether this is a
issue or a SE Linux issue. I don't believe that it is SE Linux at
With the 2.4.20 kernel, this machine froze up to 2 times per day. As
you can see, its now
operational for more than a week and doesn't have any problems. About
the performance, I cannot make an informed comment, since this is our
NFS-Server and the machine performs as well
the SE code we are using is a straight port from 2.4.20 (and should run
equally well as on 2.4.20). However other people have seen some
suggest that the problem may only occur on SE Linux machines (I don't
non-SE machines at the moment for testing).
as it did before. So .. for me, it does do as well as before.
Ok .. just for a quick comparison I compiled a stock 2.4.20 kernel on 2
machines (one with 2.4.19, one with 2.4.21rc6 kernels running). The
machines are xSeries 340 DP with 1 GHz CPUs, 1 GIG of RAM and 36 GIG
SCSI HDs, onboard AIC controller.
$ time make -j3 bzImage
Machine running 2.4.19
Machine running 2.4.21rc6
So .. again .. I cannot say that the performance has changed in any way.
