The software can also offer additional performance gains when increasing the number of server cores beyond four, which previous versions were unable to do.

When looked at the performance level, Oracle showed that MySQL 5.5 showed a 360 percent improvement in reads and writes over version 5.1 running on Linux. On Windows Server machines, that performance gain jumped over 1,500 percent. "We get higher throughput in general with 5.5.

In terms of replication, the software now includes the ability to do semi-synchronous replications. Previous versions only offered asynchronous replications, meaning the backup copy of the database would not be updated as soon as new data was entered to the original.


These were the facts given by Oracle on its new release. Now lets wait and watch for more reviews on the usage of Mysql 5.5.
