Description:
Hi,

ATR shows a performance drop for 5.1-bugteam tree (5.1.46) as compared to mysql-5.1.40sp1 (baseline) on both Linux and Windows client/server testing.

These sames drops are not seen in the MyISAM engine, and therefore is thought to be a change in behavior with the InnoDB built in.

Links and Graphs will be attached as well as configurations. 

How to repeat:
Run sysbench OLTP_RW, UPDATE KEY and UPDATE NO KEY for both 5.1.40sp1 and 5.1.46 and compare.

Version 5.1 is not supported anymore. Additionally many regression performance bugs were fixed lately, therefore I am closing this report as "Can't repeat".
