Re: [44net] amprgw routing

128MB is only 3% of 4GB. What would be the problem reserving that for a lookup table?

BTW, a nice trick for such tables is to do a mmap of /dev/zero with the proper size as a starting point, then write only the entries that are nonzero. That way the vast spaces that are only zeroes will not occupy physical memory, and when they are read by the forwarding code they read back as zeroes. Linux also has a "|MAP_ANONYMOUS" flag to obtain the same result, I don't know if BSD has that. |Rob
