Please review the My.INI settings of my PC. File Attached Below is the my.ini file of one of my PC running MySQL 5.5 with 1 GB RAM. It is not using concurrent connections and we are using a stand-alone PC for a single application and single user.

I have updated the original my.ini file. Please suggest better values for a 1 GB single user PC.

I also want to know how to flush logs and when.
You need more RAM.  Windows can barely survive with a Gig of RAM.  I would put at least 4 Gigs in the machine.
