Hello, I tried to set shaper on my local lan with HTB and rate 60mbit I used linux-2.4.22 and tried with 2.4.23rc1 - all QoS and HTB related staff compiled like modules. In both kernels the rate did not reach more than 30mbit( 3MB/sec ) When I delete shaper I can reach 9MB/sec ( about 74mbit ) if I set shaper more than 25mbit the speed did not increase :) I tried this with kernel 2.6.test9 and everything is OK shaper works on 60mbit - so I think this is problem of the current kernel Any ideas ? :) -- Regards, Svetlin Simeonov _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

One is that the HZ constant is bigger which peraps can make latencies in the kernel smaller... but I don''t know if HZ has any influence on HTB performance. Also 2.6 has NAPI, a new API for network card drivers that modifies the drivers behaviour to better reflect the usage. Its interupt driven on lighter loads, but "poll"-ing based on higher load. Anyway you can run 2.6 its not that bad. -- Damjan Georgievski jabberID: damjan@bagra.net.mk _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

See: http://bugzilla.kernel.org/show_bug.cgi?id=657 This supposed bug has yet to be acknowledged by some developers. -- Jose Luis Domingo Lopez Linux Registered User #189436 Debian Linux Sid (Linux 2.6.0-test9-mm2) _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
Hello again, I tested it with MTU 128 and it works fine :) ... for now I will set it with 2.6 kernel Thanks a lot :) on Wednesday, November 12, 2003, 12:49:01 AM, ste napisali SS> Hello, SS> I tried to set shaper on my local lan with HTB and rate 60mbit SS> I used linux-2.4.22 and tried with 2.4.23rc1 - all QoS and HTB related SS> staff compiled like modules.
