Lutz Donnerhacke <don...@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|Open |In Progress --- Comment #4 from Lutz Donnerhacke <don...@freebsd.org> --- I went through the source code and can drill the problem down to an full scan of an unsorted linked list in a given hash bucket. This eats CPU cycles for breakfast. A workaround is to increase the hash table size in sys/netinet/libalias/alias_local.h: #define LINK_TABLE_OUT_SIZE 4001 A short term solution is to make the hard coded parameters tunable. But the real solution is to find a data structure which allows sub linear access methods to the flow data. Possibly using a non blocking algorithm for access and modification. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ freebsd-ipfw@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-ipfw To unsubscribe, send any mail to "freebsd-ipfw-unsubscr...@freebsd.org"
