Changed it to 0 and restarted MySQL. Now the test will be running all night long... (a full test took 3+ weeks with 5.5 and I expect 12-14 weeks with the speed of 5.7). But as I wrote before, it seems like 5.7 causing a much higher disk load than 5.5 based on how the HD LED is flashing. It could be "off" for a long time (a second or even more) with 5.5 while now it is hardly "off" at all.

It this is the case I have never experienced this behavior. The PHP scripts write output about everything that is happening. And the speed of the output tells me how fast things goes. With 5.5 the speed was much higher right from the start (after a reboot and starting up the test). -- Jørn Dahl-Stamnes homepage: http://photo.dahl-stamnes.net/ -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/mysql
