I had looked at that list before posting this and, at least from the descriptions, none of those seemed to provide support for plugin usage with gcc.

I would like to do it at least on RHEL 6 and hopefully RHEL 5. Specifically, I'm trying to build and use odb and it requires plugin support for gcc.

comment High CPU usage with CFS?
It appears that there's something wrong with the link and the correct one is here, but I'll give those workarounds a try and see if they help performance.

@Nils Wow, that's really interesting. Assuming that this was an issue introduced in 11.2 and not just "first reported" in 11.2, then it appears that it's not CFS but a change to CFS that caused the issue. Do you know if the performance has improved or been resolved in a later release of SUSE?

@Nils Really? According to kernel version listed in the wikipedia article, CFS was introduced between version 10.3 and 11.0 (based on CFS begin merged in 2.6.23).

@rozcietrzewiacz If you take a look at the Ubuntu bug, I ran with a vanilla kernel built by Ubuntu and the linux-ck one is built from a vanilla kernel with the BFS and -ck patches applied, so I think that's about as close to a vanilla to vanilla comparison as is easily possible. I don't have access to a machine to build kernels on, so that's the best I can pull off, but the test code is available so I would love for someone to do some more fine grained testing of linux builds to see if they can isolate the issue.

@rozcietrzewiacz That was the intent of the BFS results on Ubuntu 11.10 (the last set of plots). It showed some improvement but not a complete resolution. You can also see the bug that I opened against Ubuntu here.
