Looking for bug #1506, I have found some oddity in the helper
statistics in both Squid 2.5 and 3.0:

What should be the meaning of the time column ?
Good question..
the intentions of the column is primary to show how long a blocking
request has been running, and second to show how long since the
helper was last used. With this definition it should show
now - time_when_last_request_was_sent
for unused helpers this equation does not work out that well.. so
there we should show "unused", "none" or simething similar..
OK, now is clear. So in 2.5 the statistics for standard helpers are incorrect.
Now, another question is if this makes sense.. can produce somewhat
confusing numbers as it's effectively overloading two semantically
different values in the same column, and even more so on stateful
helpers due to them being reserved waiting for the client..
And there is another problem: the range of the values can be very
large, starting from milliseconds to minutes: very confusing.
I have a proposal:
- In the time column to place always the time (in seconds) from the
last usage, if any
- In the flags column, for the 'B' flag, use a 'B:time' syntax for
the blocking time (in milliseconds)
This should be less confusing.

Guido
