It gets far, far better than this. I misunderstood some of the details of the article the first time I read it. It turns out that the morons have written an SMTP MTA that keeps all writes in memory and never flushes them to disk. When the ignorance of RFCs and standards is at this intrastellar level, you can forget everything you wanted to talk about with regards to OS tuning. None of that means anything whatsoever, when compared to a program that completely and totally violates the single most fundamental principle of the standards. The programmers may have known something about how an async, poll()-based application can be written, but they very, very clearly knew absolutely nothing whatsoever about writing an SMTP MTA. Go home, the party's over. These guys are so bloody clue-free that it's no longer worth the effort even contemplating the thought of attempting to help them learn how things ought to be done. -- Brad Knowles, /* efdtt.c Author: Charles M.
