I have a VPS with apache, mysql and PHP installed with out-of-the-box configuration.
There seems to be a problem with mysql - it's incredibly slow. Single update query takes [url removed, login to view] to complete.
Disk I/O is good:
1073741824 bytes (1.1 GB) copied, 14.207 s, 75.6 MB/s
and php performance is also very good - a test script completes in 5 seconds, whereas it takes my Intel i7 SSD windows machine 17s to complete it .
So I guess it's related to mysql setup and configuration. When I run the query through my windows command line (my local server) I get this:
Query OK, 1 row affected (0.01 sec)
Rows matched: 1 Changed: 1 Warnings: 0
Whereas when it is run on the VPS server, it's like this:
Query OK, 0 rows affected (0.55 sec)
Your job would be to find and eliminate the problem.
