Mavibot Time difference in build
Hi
Just for the record. Looks like this is the test taking much longer in
JDK 1.7:
Running org.apache.directory.mavibot.btree.PersistedBTreeBrowseTest
Browse Forward for 9 = 4320
Browe backward for 9 = 5125
Tests run: 25, Failures: 0, Errors: 0, Skipped: 2, Time elapsed: 235.79
sec - in org.apache.directory.mavibot.btree.PersistedBTreeBrowseTest
whilst in JDK 1.8:
Running org.apache.directory.mavibot.btree.PersistedBTreeBrowseTest
Browse Forward for 9 = 3861
Browe backward for 9 = 4990
Tests run: 25, Failures: 0, Errors: 0, Skipped: 2, Time elapsed: 16.635
sec - in org.apache.directory.mavibot.btree.PersistedBTreeBrowseTest
Regards
Felix

I had it with an SSD, but fsync could be an issue anyway. It could also be
an JDK implementation 'issue' for linux JDK. That's why I wonder if it's
reproduceable by anybody else.

I can't reproduce this on my laptop (which has an SSD). But I think I
saw that before on a machine with spindle HDD. Maybe it has to do with
too many fsync when writing to disk?
Kind Regards,
Stefan

Very interesting ! Would like to know why the mentioned test runs so much faster on JDK1.8 than JDK1.7.
Regards,
Kai
