I have extended the class a bit. It is now possible to choose from four different tests. Test 0 is the one Oleg wrote. It reads from a MimeTokenStream until its end is reached. Test 1 uses a MimeStreamParser and reports to an empty AbstractContentHandler. Test 2 uses a MimeStreamParser and reports to an empty SimpleContentHandler. Test 3 creates Message objects in memory. On my machine the results are: Test 0: ~ 8 sec Test 1: ~ 8 sec Test 2: ~ 41 sec Test 3: ~ 47 sec So it looks like parsing the header fields consumes about 80 percent of test 2. The difference between #2 and 3 is probably caused by copying the message bodies into Storage objects. Maybe the header fields should be parsed lazily? Does anybody have a better idea? Markus PS: I have also written a test that creates a JavaMail MimeMessage. That takes about 12 seconds on my machine. --------------------------------------------------------------------- To unsubscribe, e-mail: server-dev-unsubscr...@james.apache.org For additional commands, e-mail: server-dev-h...@james.apache.org
