https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=219124 --- Comment #4 from Sean Bruno <sbruno@FreeBSD.org> --- I'm guessing that this is an initialization problem. The hash is being setup to handle way more elements than is really needed in here. % wc -l /etc/services 2495 /etc/services HASHINFO hinfo = { .bsize = 256, .ffactor = 4, .nelem = 32768, .cachesize = 1024, .hash = NULL, .lorder = 0 }; If I change the HASHINFO to be slightly less over engineered (and less future proof), I can get the *empty* services file down to 260k, but that's not really a huge improvement for a basically empty file. Should it be that big? I didn't really think I was going to have to go and learn berkley DB this week. :-) Index: services_mkdb.c =================================================================== --- services_mkdb.c (revision 318297) +++ services_mkdb.c (working copy) @@ -68,10 +68,10 @@ static void usage(void); HASHINFO hinfo = { - .bsize = 256, - .ffactor = 4, - .nelem = 32768, - .cachesize = 1024, + .bsize = 48, + .ffactor = 1, + .nelem = 4096, + .cachesize = 256, .hash = NULL, .lorder = 0 }; -rw-r--r-- 1 sbruno sbruno 262720 May 15 12:04 services.db -- You are receiving this mail because: You are the assignee for the bug.
