Just so you don't underestimate a requirement ... :-)
Underestimating is desirable here. User gives upper bound - observe it!
(assume we are checking positive numbers ;-)
We are, the variable in question, is unsigned.
Actually, I now have this nice

Hi all,
I have released http://bei.bof.de/cttest-0.2.tar.gz. It is now easier
to modify the list of sizes and hashes that should be plotted, and
there's timing code for the hash functions, together with average
used list length

Also with this idea of using power of (^), we tested the abcd hash using
power of instead of just adding the values up:
static u32 hash_abcd_power(struct ct_key *key)
{
u32 res;

I guess you all are begining to get a little tired of my mails :-). Anyhow

Hi,
I've also done some plotting.
about 400 student-machines behind router, it's summer now so there's not
as much traffic as the rest of the year, only ~28k entries.
hashsize is 16384 with default ip_conntrack_max of 131072.

I collected this data 5am during absolut low time. I'll try again later
at primetime :-)
Here is a new stat with about 85K entries:

- make the hash bucket count at least individible by 2. This should go
as a strong suggestion into the documentation, and should be implemented
in the default initialization code. Anybody volunteering for one or
the other?

Hi all,
I have put a tarball at http://bei.bof.de/cttest-0.1.tar.gz
Unpack, look at README, and reproduce the gnuplot pictures I have
mentioned earlier today (at http://bei.bof.de/ex1/)
I would love to see results from other
