I didn't add write queries to this master, so I only have the 4 sources (I removed 2 sources since I enable sync_binlog), so I mean 4 transactions in parallel at max ... > Of course, it could also be that the fdatasync() at commit is not a > bottlenect, which would also result in Binlog_commits =~ > Binlog_group_commits.

If interested I found last commit for WL#4925 by Yoshinori here : http://lists.mysql.com/commits/113309 I'm looking for adding a SSD drive to those servers for binlogs. -- Greg
