Hi, I'm trying to tune dummynet to shape a lot of traffic. I saw some opinions that the following patch will improve dummynet performance: in /sys/netinet/ipfw/ip_dummynet.c -#define HASHSIZE 16 -#define HASH(num) ((((num) >> 8) ^ ((num) >> 4) ^ (num)) & 0x0f) +#define HASHSIZE 256 +#define HASH(num) ((((num) >> 8) ^ ((num) >> 4) ^ (num)) & 0xff) The question is: will it increase dummynet performance? What will it actually do internally (luigi, question for you :) ? Best regards, Andrey Kropachev
