/etc/vservers/<server name>/schedule should contain 6 lines:

1: fill rate

2: fill interval

3: amount of "tokens" on start

4: minimum number of tokens in token bucket

5: maximum number of tokens

Each <2> jiffies <1> tokens will be put into bucket. Any tokens more than <5> are spilled.

Processes will be back from "on hold" when in bucket is more than <4>.

You should aim that the sum of (fill rate / fill interval) adds up to roughly the number of processors in your system. If the fill interval is too long, it might make performance erratic. Setting it as small as 1 or 2 is fine. It only actually recalculates the amount when it has to. Of course, with a fill interval of such a small value you're dishing out large chunks of the system :)

<romke> mugwump: so, wouldn't be better if fill interval be more like 10-20 ? and fill rate proportionally greater?

<mugwump> it makes little difference. Just don't go expecting smooth scheduling behaviour when it gets near HZ (100 or 1000)
