Percona 5.1.58-12.9 Highlights
Performance Improvements
-
fsync()has been replaced withfdatasync()to improve perfomance where possible. The former is intended to sync the metadata of the file also (size, name, access time, etc.), but for the transaction log and the doublewrite buffer, such sync of metadata isn’t needed. Bug Fixed: #803270 (Yasufumi Kinoshita).
