the only reasons I can think about why not to use 64bit Kernel support are:
- You need a machine that really takes advantage of the technology. With or above 4GB RAM you should switch to 64Bit.
- 64Bit Kernel support is rather new and there are still some unknown issues to be dscovered and fixed in the Linux Kernel and tools
- At the ASG there are very few (if any) daemons that already take advantage of 64Bit. The main advantage is increased allocateable memory (increased max connections etc.). It's only the Kernel that makes the difference at the ASG as of now. You can also easily switch kernels by (un)/installing the corresponding kernel RPMs.
No words about performance from me ;-). Not that I wouldn' t tell you, just a lack of the necessary figures.
64bit support has been in the linux kernel for quite some time and is very stable. I've personally been running 64bit linux since early 2005.
Hi TheDrew!
That may be the case for you, but, depending on the setup and variety of drivers etc., 64Bit Linux Kernel can't yet catch up with stability and compatbility of the 32Bit version. Especially support for edge-case usage scenarios like Bridging for example (I just mention this because it was the last 64Bit related problem I discovered just a week ago), there are still some issues with 64Bit Linux Kernel or the tools.
