Re: Swap or I/O Improvement in Fedora 8?

Dear all,

I've tried Fedora 8 to run some applications that require large amount
of memory. Since my machine only contains 2GB RAM, I resort to a very
large swap partition (32GB). I found that the performance has been much
improved as compared with Fedora 7. Are there any changes on the
swapping algorithm, or any improvement in the I/O of Fedora 8 over its
predecessors, that accounts for this result? (If it's the latter case, I
suppose common read/write triggered by the program code will be
benefited as well, but I have not tried this.)

Best Regards,
LaBird (Benny).

They both use the same kernel so there shouldn't be any difference in the
swap algorithms. The memory usage might be different, if you are using
less memory with F8 then you would do less swapping. How much memory do
you actually need? You really really don't want to be swapping, buy more
RAM.
