I have PC box with Core 2 Quad, P35 chipset and 4 GB of RAM (2+2 GB) with 32-bit OpenSuSE 10.3 and kernel-default installed. Why did you do that?
The proper kernel for that machine is the x86_64, NOT 32 bit.
These processors work just fine in 32-bit mode and support PAE in that mode.
It will give access to all your memory and about a 20 to 30% speed boost with a typical mix of software.
As we've been through this before, I'll just say that this is by no means the fact John presents it to be.
A better rule of thumb is never run a 64-bit processor for tasks that don't require the address space it affords.
Good advice - I've got a busy server at the office, with 4 CPUs and 16 GB RAM - it's running a 64 bit suse OS, and it really needs the bigger address space. OTOH after seeing 18 months of thoroughly unimpressive performance from the mail server on my home network, a machine with 1 GB RAM, I upgraded from suse 10.2/64 to suse 10.3/32 and it performs much better with the 32 bit OS. Use 64-bit where it makes sense: on a machine big enough to actually benefit from the 64 bit OS, where you don't depend on any 3rd party software that does not play well with 64 bits (been there, done that) Joe -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
