Re: Poor performance of MySQL 5.5

innodb_flush_log_at_trx_commit=1 -- The disk subsystem, drivers, OS settings, etc play a big role. I would not expect 64-bit, number of cores, etc to have much impact.

innodb_flush_log_at_trx_commit=1 slows your "transactions per second" to roughly your "writes per second", which (for typical systems) is about 150K/hour.

If INSERTs are your main activity, then any of these can give you on the order of 10x speedup:
* Multiple INSERTs per BEGIN...COMMIT
* Batching 100 rows per INSERT statement
* Using LOAD DATA instead of INSERT.
