Are there any benchmarks of NDB with a large number of clients?

I'm specifically curious about the scalability of a distributed all -memory system with a large transaction throughput (say 5-10k clients).

10k clients per box might be a bit hard due to the fact that you guys are using threads...... and there are per-thread memory requirements.

Hi,

Are you referring to SQL or ndbapi clients?

Ndbapi has possibility to run several transactions in parallel wo/ threads using the "asynchronous"-interface.

Many/most internal benchmark programs for ndbapi uses this feature... I.e they don't really have many clients, but can have many parallel
transactions...
