Dont amd processors use the x86 instruction set already...?
the main difference in archetecture is the 3d/multimedia instructions on
amd's k6/2 processor.
Unless you have a 3d acelerator in your raq...?
I'm not an expert in this (which is why I asked), but it seems that
since the 386, there has been improvements to the architecture beyond
just the multimedia instructions. Pipelining, memory handling, FPUs,
cache have all changed a lot.
Obviously, things work just fine now, but part of the compiling process
involves an "optimizer" process. It seems like there might be some
optimizations available.
As far as multimedia goes, one of our servers handles creating Flash and
Gif images on the fly. Does that count as something that can be
multimedia-enhanced?
Additionally, I hear compiling PHP statically into Apache improves
performance by 10%. PHP has a lot of dynamic modules, is it better to
load these modules statically into PHP, or does the memory usage start
to become a problem? (or possibly some other reason not to do it...)
I'm not necessarily looking for all the answers, I just don't want to
waste my time digging, testing, and experimenting if someone has already
done this and found the benefits negligible. Now days, with hardware as
cheap as it is, I could throw another computer in there cheaper than if
I had spent 25 hours on the task just to find out there was a 3.2%
improvement in speed.
Thanks for any help you can give.
