Oracle has sent out a
proclaiming the virtues of its new kernel. "Based
on the combined efforts of Oracle's Linux, Database, Middleware, and
Hardware engineering teams, the Unbreakable Enterprise Kernel is: Fast:
More than 75 percent performance gain demonstrated in OLTP performance
tests over a Red Hat Compatible Kernel; 200 percent speedup of Infiniband
messaging; 137 percent faster solid state disk access.
" Much of the
gain may come from using 2.6.32 as the base instead of 2.6.18, but it's
hard to tell for sure; source for this kernel does not seem to be available
for download as of this writing.
This is an interesting move in that it reintroduces competition at the
kernel level - something distributors have not emphasized in recent years -
and it demonstrates an intent to move a bit further away from the RHEL base
that Oracle uses to build its offering.
