Hi

Which is it better to have - swapfile partition or swapfile?

I have both, on a SSD. Thing is, I can write 10x faster to the file than I =
can
to the partition. With a 512b block size, it can write at 17MB/s to the
partition, and about 120-130MB/s to the swapfile, as reported by dd.

Historically, ISTR that it was recommended to have several swap partitions =
on
the fastest disks available, and that swapfile was slower than a partition
because of something like fat translation. Is this still the case nowadays?
Is there a better way of measuring swap speed than dd?

thanks,

J.
