This is all subject to hardware and specific transactions, but 
_normally_ Galera can sustain considerably higher trx rates than 
standard MySQL master-slave replication on the same hardware and load. 
This is mostly due to parallel applying and relaxed 
innodn_flush_log_at_trx_commit.

But I have seen 3000-5000 trx/sec in some clusters and in some 
synthetic tests it could achieve up to 50K autocommit updates per second 
in 1Gb network. So trx rate itself is not an issue there. What matters 
is how heavy those transactions are for your hardware.

Unfortunately I have no say in this. This question should be directed 
to Monty Program.
