Hello,
I have missed the previous discussion, but
I think that this issue comes up quite regularly.
If you need to swap, you want to minimize head
movement and maximize throughput. So you can IMHO:
- use a different disk than where the most
of your data activity occurs
- if this is impossible, try to keep the swap
area close to your data
I think that the most appropriate solution
would be a single continuous (or very little
fragmented) file in the middle of your data
partition. I have no idea whether this is
possible to achieve with common available
tools. In addition, this partition should
be at the outer side of the disk.
But the main point is always: if the working
set ouf your typical process mix does not fit
into the real memory, you have a problem. The
speed of swap should actually be of little
interest for the typical tasks on a given
system - if it matters, something is wrong
and you most probably need more RAM. Given
that, the KISS principle of a swap partition
can be an advantage and maybe there is no point
in optimising when the real cause lies somewhere
else.
