Hi,

I get Linode's "disk I/O threshold exceeded" a few times a day, with the warning threshold set on the default 1000 ops/sec over two hours.

I don't really have a feeling for how bad 1000 ops/sec is - I can imagine what effect 90% CPU use or 90% memory use would have on my machine, but not whether 1000 disk i/o operations per second is worryingly high or not.

So, wise Linode users - should I have a go at optimising my scripts to keep my I/O rate below this threshold, or should I just bump the threshold up a bit and stop worrying?

The threshold is just a guide -- the actual I/O load depends on what you are doing with the disk (read vs write, big vs small blocks, etc) -- so it really serves as an alarm when things go badly wrong (swap thrashing or similar). If you box is performing OK, bump the limit up a bit.
