Hello,

What type of a query is it? (i.e. complex join)

Perhaps a sample query?

Thanks,

I have an issue with a web-application i have, i run mysql cluster 2 nodes, 1 mgmd. If i backup the database and put it on an other server as simple mysql (not clustered) it works perfectly with good performances but on the production server, running mysql-cluster mysql sometimes take up to 50% of cpu usage for a query. Did anyone ever seen this and can someone orient me on what's happening with this ?

Thanks :)

Pierre.
