I understand now, in other words, take RHEL6 kernel and run it on RHEL5 - under specific workload, you may achieve 75% increase.
Thanks everyone for your input. -----Original Message----- From: rhelv5-list-boun...@redhat.com [mailto:rhelv5-list-boun...@redhat.com] On Behalf Of Leinweber, James Sent: Tuesday, February 21, 2012 4:52 PM To: Red Hat Enterprise Linux 5 (Tikanga) discussion mailing-list Subject: Re: [rhelv5-list] RedHat Linux VS competitor > ... as if Oracle Linux is 75% faster in comparison to relative RHEL [5] Think of it as a Redhat 5 userland with a Redhat 6 kernel, to a first approximation. If they started from 2.6.32 and cherry picked a few upstream items beyond that, they have roughly 8 years of performance enhancements past the Redhat-5 2.6.18 era kernels to benefit from. They might indeed have managed 75% speedup for some workloads. The difference would be less impressive against Redhat 6.2, or Fedora, or Ubuntu 10.04. -- Jim Leinweber State Laboratory of Hygiene, University of Wisconsin - Madison <jim.leinwe...@slh.wisc.edu> phone +1 608 221 6281 PGP fp: D573 AF7D F484 EE2A F0B6 B7DB A870 7518 F87D A0D1 _______________________________________________ rhelv5-list mailing list rhelv5-list@redhat.com https://www.redhat.com/mailman/listinfo/rhelv5-list _______________________________________________ rhelv5-list mailing list rhelv5-list@redhat.com https://www.redhat.com/mailman/listinfo/rhelv5-list
