Something to consider if you're using MySQL with RAID: In case innodb_flush_log_at_trx_commit=1 (default) this will be synchronous operation and thread will need to wait for it to complete before continuing. Though in decent systems you have battery backed up cache so this wait is not long. In case innodb_flush_log_at_trx_commit is set to 0 or 2 physical IO will be happening in background giving yet another request which can be executed in parallel in the background.

In MySQL, a UNIQUE index is one in which all values in the index must be distinct. An
