That was just a mistype i typed in actualy your test config for htb, 
modified for my expalme purposes :))
this is the actual config:

tc -s -d class show dev eth0:
-----------

MARK       all  -- srchost2  anywhere           MARK set 0x2 

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination         
MARK       all  --  anywhere 		srchost1         MARK set 0x1 
MARK       all  --  anywhere 		srchost2 MARK set 0x2 

-----------

Also: whe I mark pakets for example only on OUTPUT chain, it will apply 
only to packets from me? so I should do it for in and out right?

Anyway with this config when I download from srchost1 (I use wget to 
measure) via ftp wget shows from 140 to 240 KB/s
and for srchost2 via http I get from 70 to 100 KB/s. nothing like I 
expected :)

Thanks
