Greetings Dariusz,
: ive got problems with my network (120 people)
: ive got big pings (300ms)m whereas there are normally about 19ms.
: i do not know if my qos is proper (fast i mean).
:
: www.tdi.pozman.pl/fir2 - my qos
: www.tdi.pozman.pl/rules - my firewall
After examining 'fir2', which shows an HTB class structure listed below, I
think you don't quite understand the guarantees and the borrowing model of
HTB.
your Internet bound traffic (1:2) -- - - - --> rate ceil
|
+--------+--------+--------+--------+-------+
1:N | 1:7 | 1:6 | 1:5 | 1:4 |
| [ lots of | | | +--> 128kbit 256kbit
| classes | | +-- - - - -> 128kbit 256kbit
| here ] | +- - - - - - - - - -> 128kbit 256kbit
| +-- - - - - - - - - - - - - -> 128kbit 256kbit
| ... ...
+-- - - - - - - - - - - - - - - - - - - - - - -> 128kbit 256kbit
In your case, N=163 (although I didn't check that every class was
created with the same rate/bandwidth). The problem you are having is that
the borrowing (and hence, shaping) model never gets a chance to go into
effect.
Every leaf class (1:4 through 1:166) is guaranteed 128kbit. Your QoS
setup is actually not helping you at all! It's configured to guarantee
around 19mbit (128kbit * 163 guarantees).
Given your available Internet bandwidth, it should work out a bit better
for you if you slim down the total number of classes and lump a few
handfuls of users in each class with an embedded SFQ. You may find that
Stef's rules for HTB shaping are quite handy [0], and also my HTB
description [1].
Good luck,
-Martin
