Hi all, I've a MySQL installed on a Cash Regiter with 4GB of RAM and an Hard Disk with low performance. I can't upgrade the hardware of this machine.
The engine of MySQL is InnoDB and the configuration is quite standard.
Every night the PC is restarted at 5:00AM so the mySQL server restart.
On this machine I've a database with something like 30 tables and the database is about 500MB.
For the first hours of work the program that run on it and use MySQL have good performance that slow down after 5-6 hours of work, then begin to slow down.
The only way to restore the inital performance is to restart the MySQL server.
Any idea??
Running the SHOW LOG command at interval I have thiS situation:
COUNTER VALUES AT 10:30 .. AFTER 10 MINUTES .. AFTER 20 MINUTES .. AFTER 30 MINUTES
