I have been adjusting the source to increase the negative cache
size, for when quering against rbl's
From my stats, it seems to me that the negative cache is not part
of the positive cache, but totally different cache area/counters.
So it seems the real max-cache-size = max-cache-size * 110% (as the
negative cache is hard coded at 10% of the max-cache-size currently).
I adjusted my source, so I could specify the negative cache size as
a percentage of the max-cache-size, but as it seems to be
different, I'm wondering if my patch (before I submit it in a
feature request) should be changed to a negative-cache-size, that
would just default to the current behavure.
Concrete numbers are usually better than percentages of other numbers.
In any case, please submit your patch at wiki.powerdns.com so people
can look at it!
I'll submit it sometime next week, I've been playing with it, and
seeing how it works, it does seem to be seperate from stats point of
view, and I had decided next time I look at it, to change it from
percent to just a raw number, and just leave the default as a percent
if undefined, so there isn't any suprises on an upgrade.
