First: thank you for sparing so much time with me. > There are 3 major factors determining your performance: 1) the > speed of the > CPU, 2) the size if your RAM, and 3) the data transfer speed of > your disks.
I thought that the size of tables in the db would have made a difference. >From the analysis you did and from my tests it doesn't look so... > 5) If your application is smart enough, you can split your data over > several servers. This would be a SERIOUS performance increase. In fact I'm writing a jdbc driver in java that I hope will be included in c-jdbc (http://c-jdbc.objectweb.org/), which is a java database cluster middleware (check it out, it seems very interesting) > 2) you can move parts of your data to other disks.

That is what I am trying right now, but I am having problems because it seems that there is no disk I/O if I access by index on my tables, even if I access most of the table data (while with a table scan disks work as expected). Does it happen because I have 1Gb of Ram? If yes: I know that this sounds like a silly question but... How can I "fill" the memory of my machine so it doesn't cache data? (I can't just remove memory, I don't have physical access to the machine) Thank you -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
