Re: Very slow SELECT

I have found a problem. When i lanched the Cluster the first time, i forced the 100Mb on the switch. After, i put 'auto' and it was better. But not realy good.

When i lanch super-smack (250 clients, 50 query per client) benchmark with MyISAM, I have +/- 25K query/second (only select), with NDB i have 700 q/s.

I have "engine_condition_pushdown=1" on the my.cf.

I added 2 nodes, and it's the same with super-smack.

And, the Cluster use only 1Mb when i lanch super-smack.

I have "play" with ndb option, and nothing.

Any idea ?
