Yes, of course. Run multiple copies of your script if it generates particularly representative (of your intended work-load) content. Otherwise use smtp-source(1) with a suitable number of parallel streams. Measurements of single-stream performance just measure single transaction latency on a lightly loaded server, not peak server throughput. -- Viktor.
