Hi, during analyzing my webserver logfiles I've realized, that one ipv6logconv run requires more than 20 min per. This was the start for profiling this tool and implement a major speed improvment. 2 changes were made: a) ipv6logconv: - implement a lookup cache for speed-up saved around 50% before implenting b) saves around 20% after implementing b) b) lib/libipv4addr databases/ipv4-assignment/dbipv4addr_assignment.h - add a hint table for speed-up IPv4 registry lookups speed up by 10 times! New version is now in CVS, if no problems would be reported, I will publish version 0.49 next weekend. For those who didn't know what ipv6logconv can do for you, take a look at the statistics pages on <http://mirrors.bieringer.de/> Hope this helps, Peter -- Dr. Peter Bieringer http://www.bieringer.de/pb/ GPG/PGP Key 0x958F422D mailto: pb at bieringer dot de Deep Space 6 Co-Founder and Core Member http://www.deepspace6.net/
