Yeah, the overhead of fork and not having to have shared memory segments is where i see the speedup. I belive the rest of the speedup comes from chaning out Glist and some other things. But I have some neat things up my sleave..etc. I accualy think I just found a faster mime parser that is GPL'ed than GMime. it is stable and well tested as well as thread-safe which GMime may or maynot be acording to thier docs...etc. I will see what I feel like when I get to that point.. :) The other library is called EPS: http://www.inter7.com/index.php?page=eps I guess the mime stuff is a RFC...etc. > > BTW, I'm not trying to be negative about your work, I'm just trying to > discuss the options and get down to the real details.

Yeah I know not thinking that at all, I am doing it for someone else weather or not the dbmail developers decied to use any or all of it. So it works out for all of us :) You can thank my customer more they are the ones paying me to fiddle with it :P Thanks, Leif > > Thanks for the hard work! > > Matthew > > > _______________________________________________ > Dbmail-dev mailing list > Dbmail-dev@dbmail.org > http://twister.fastxs.net/mailman/listinfo/dbmail-dev >
