Subject: HTB vs HFSC, HTB is highly inaccurate
Date: Sun, 8 Mar 2009 20:45:39 +0200	[thread overview]
Message-ID: <200903082045.39083.denys@visp.net.lb> (raw)

Hi again

I test again HTB and HFSC, this time in very simple case.

Regarding HTB - i try without quantum, with different values, without and with 
cburst (big and small), with HZ=1000 and default, hysteresis on and off - it 
is almost same result. 

While i set limit at 57, it can reach 61. HFSC results is perfect.

Here is graph snapshopts.

You can see points where HTB enabled. Other points if HFSC.

Scripts source is:
