Performance

TTP has performance of approximately 211 lines per millisecond on Intel Core i5-3320M CPU @ 2.6GHz (CPU End-of-Life July 2014) if running in multiprocess mode with all function pre-cached by Python, meaning that dataset of 3,262,464 lines can be parsed in under 16 seconds best case and under 22 seconds worst case.

Multiprocessing mode restrictions

While multiprocessing mode has obvious processing speed increase benefits, it comes with several restrictions.

• per_template results mode not supported with multiprocessing as no results shared between processes
• global variables are not shared between processes and have per-process significance (name space), this is due to the fact that global vars not shared between processes
