some things in this thread.
1) as Rob pointed out, you are slowing down your linux
server on purpose. A swap device to disk maybe can do 200 swaps
per second, so ok, add 3, and you can do 600.
With vdisk, it could be 40,000 per second - so linux doesn't
notice it is swapping.
2) you do not have t

Yes, and that is where it makes a difference. On discrete servers it
may make sense to tune your co

Sure. And that's where the different priorities make sense to avoid
infinite growth of the footprint of that VD
If you're running under VM, make the swap devices a virtual disk. They
can handle a significantly higher load than the real disk.

I tracked down a copy of the actual report from the performance guy, and it
turns out we've been (partially) barking up the wrong tree. Sorry for the
confusion.
The real story is that the large swap partition DEVICE was 100% BUSY during
part of the test. The original summary report said 100
