Dear friends, thanks for the last advices about TBF. After reading the tbf.pdf document I got a better insight of the problems I had trying to limit the bandwith on my testbed with a high resolution. The question I have now is: Would I get an immediatly better resolution result if I change the #define HZ to 1000 for my Linux box? I have a Pentium Celeron 700 MHz, and I would like to see the tbf working like: send a 1000 bytes packet -> wait 10ms -> send a 1000 bytes packet -> wait 10ms .... So if I change the file /usr/src/linux/include/asm-i386/param.h: #define HZ 100 to #define HZ 1000 and simply recompile the kernel, would tc work with better resolution? Thanks again, Fernando. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
