Dear Jonathan!

I guess I didn't expain well.. Data nodes are placed on separate box with 2Gb of ram each. And those boxes does not make any problems - no much load. But load comes from API nodes, which are hosted on the same box, as webserver. Am I doing something wrong? How is connection beeing distributed between API and DB nodes?

I have tried MySQL 5, beta version. Our test results are just amazing - much-much faster, than we used DB<->API nodes.. And mysqld process almost does not use RAM, although it's just 1 PC that holds all connections to the database from 3 webservers!!! On the same tests mysqld on API nodes took a lot of RAM and test time was much longer (comparing 0.1sec on MySQL 5 to 6-60sec using cluster).

Probably I am doing something wrong or I don't understand something, my logic is not enough to understand that.. And my boss is saying - we should try to make cluster to run faster..

How is it better to make - have many API nodes or have just 1 powerfull box with lots of RAM for API node? Why mysqld process takes so much memory? It does not keep database, does it?
