[LARTC] ESFQ not so fair?

["Michał Margula" <alchemyx@uznam.net.pl>]

Hello!

	I am using since yesterday ESFQ instead of N HTB queues. It mostly 
works OK, but when somebody is using one single sesion (for example 
downloading file via FTP), it gets weird speed. For example it is 20 
kilobytes pres second, then drops down to 9, then 20 again, and then 
slowly to 0 and stops. But when using download accelererator of some 
kind or bittorrent client which uses many connections, speed seems to be 
stable.

I am using esfq that way:

	qdisc add dev eth0 parent 1:4 handle 4:0 esfq perturb 600 hash fwmark 
divisor 13
	qdisc add dev eth1 parent 1:2 handle 2:0 esfq perturb 600 hash dst 
divisor 13

On eth0 every IP is marked with different value by IPMARK module. On 
eth1 it is not necessary so I use dst hash. I have more values than 2^13 
so I can't use direct hash.

Any ideas? Is it possible to use bigger divisor or algorithm is not 
designed to deal with bigger hash? Any ideas will be appreciated!
