Hi,
I've done some benchmarking of the recent performance improvements in
trunk vs Mime4j 0.3. I must say that the result is very promising! :)
I did my tests on about 130000 messages, most of them less than 10 kB
in size. All message files had been cached by the Linux file cache
when I conducted the tests so it doesn't take the disk I/O in
consideration. I guess I should also run the tests without the cache
but I don't know how to force it to flush. The test uses the SAX-like
parser interface and a ContentHandler which does nothing (only
consumes the data).
Here are the 0.3 results:
Statistics for all messages (130606)
Total duration: 23830 ms
Average duration: 0.182457 ms
Statistics for all messages (124480) more than 0 kB and less than 10
kB in size
Total duration: 15264 ms
Average duration: 0.122622 ms
Statistics for all messages (5934) more than 10 kB and less than 100
kB in size
Total duration: 5173 ms
Average duration: 0.871756 ms
Statistics for all messages (161) more than 100 kB and less than
1000 kB in size
Total duration: 1033 ms
Average duration: 6.416149 ms
Statistics for all messages (31) more than 1000 kB in size
Total duration: 2360 ms
Average duration: 76.129032 ms
And here are the 0.4 results:
Statistics for all messages (130606)
Total duration: 10069 ms
Average duration: 0.077094 ms
Statistics for all messages (124480) more than 0 kB and less than 10
kB in size
Total duration: 8583 ms
Average duration: 0.068951 ms
Statistics for all messages (5934) more than 10 kB and less than 100
kB in size
Total duration: 1106 ms
Average duration: 0.186384 ms
Statistics for all messages (161) more than 100 kB and less than
1000 kB in size
Total duration: 115 ms
Average duration: 0.714286 ms
Statistics for all messages (31) more than 1000 kB in size
Total duration: 265 ms
Average duration: 8.548387 ms
As you can see 0.4 is about twice as fast on messages less than 10 kB
in size and about 10 times faster for messages larger than 100 kB.
That is quite amazing!
Please let me know if my benchmarking method is flawed in any way.
I'm attaching the source code of the test tool.
