hi,
I wasn't shoure in with section this thread belongs.. so sorry if I have missplaced it.
Iam wondering is there some notisible perfomance enchantment in compiling kernel?
would fedora run faster in that case?

the short answer to this question is no.


the longer answer is that on some architectures you may get a few percent performance increase but it's usually not worth the hassle.

Reason you may need to custom cmpile is to enable features the default precompiled kernels do not have enabled.
or
You know your system and hardware and remove the unneeded modules and kernel options to have more space on limited drive size.
or
There is a bug in the current kernel that is causing issue under linux. Upgrading or sometimes downgrading the kernel will return the system to a more stable configuration.

For me I need to custom compile based on hardware installed in the machine and have done the other two depending on the issue.
