Delay pool problem?

According to the docs, the max/restore/current figures are specified in
characters per second. So to achieve the figures as shown below by cache
manager would indicate a link of at least a meg would it not? We dont
quite have that much bandwith so I'm curious as to what is going on? (I
set the high max/restore to see what the current figure would show).

Using latest 2.2.5 (i think) with patch #1 (that fixes the linux poll
problem).
any help appreaciated.
thanks
