Starting with this benchmark report: http://www.percona.com/files/white-papers/clustrix-tpcc-mysq...
Basically, InfiniSQL does not currently support complex indices, so it can't do a TPC-like transaction.
The maximum throughput on 9 nodes is 128,114 per node per second. I don't know if that's 4 or 8 core nodes. If roughly 10% of transactions are multi-node transactions, then 12,811/node/s for multi-node, and 115,303/node/s for single-node transactions.
I don't know if full redundancy for Clustrix was configured, or a hot spare, so I don't know how many actual usable nodes were configured, but likely fewer than 9. But I don't know the precise number.
Roughly 10% of those transactions are contain records on multiple nodes. Based on 9 nodes, that means about 12811/node/s for distributed transactions combined with 115303/node/s for single node transactions.
InfiniSQL maxsed at over 530,000 multi-node transactions on 12 x 4-core nodes. http://www.infinisql.org/blog/2013/1112/benchmarking-infinis...
That's 44,167 per node.
---------
These were not apples-apples benchmarks, but Clustrix performed about 12,000 multi-node transactions per node per second, along with a whole bunch more single-node transactions.
I don't know how it would perform on the benchmark I used. And I intend to do a tpcc benchmark once InfiniSQL is capable of complex keys (among whatever else it it currently is missing).
