So please find attached another benchmark for that case.
The 3 different patchsets tested are:
- master
- fixed (David's original patch)
- adjust (Thomas growing blocks patch)
So it looks like tuning malloc for this would be very benificial for any kind
of allocation, and by doing so we reduce the problems seen with the growing
blocks patch to next to nothing, while keeping the ability to not allocate too
much memory from the get go.
I would like to try to implement some dynamic glibc malloc tuning, if that is
something we don't reject on principle from the get go.
