Heres the thing. For pretty much any sane combination of disk and CPU one is likley to find the hashing process is going to be faster than writing that to disk by a factor of about 8. Thus if you server isn't cpu bound this is a net win.
> > These are small times, but they start to add up. we are talking an addition of about 3% cpu load on an absolutely maxed out 100mbit line. IE if you are getting 320 gigabytes of email per hour or so you are going to see a 3% increase in cpu use. (thats assuming the 320gb of email is all new stuff, if any of it is actually replicated then the cpu use will probably go down with the overhead of your database actually storing that stuff) > > I really like dbmail.

If you have 4 accounts then you won't even notice it. If your emails are smaller then the time will be smaller too. IE a standard machine will process about 50 Mega Bytes per second with a 20% cpu load. If the file in question is less than 50 megabytes the time taken to hash it will be less as well. IE a 5mb email would hash in .1 of a second at 20% cpu. If it gets the whole CPU then it will be processed in 0.02 seconds. Really Really its not going to matter. _______________________________________________ DBmail mailing list [email protected] https://mailman.fastxs.nl/mailman/listinfo/dbmail
