Alex,
did you change any my.cnf parameters? Version .39 should
actually be a littel bit faster than .38.
What does Unix 'top' say? What are the CPU usage %?
The biggest change performance-wise in .39 is that
you can now specify the parameter
innodb_unix_file_flush_method
in my.cnf.
You could try the following values for it:
innodb_unix_file_flush_method=O_DSYNC
or
innodb_unix_file_flush_method=littlesync
Does it work fast now?
Regards,
Heikki
