Dummynet tuning

[Andrey Kropachev]

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,
