Both writing to perf.log frequently as well as GetTimestamp aren't free and hurt performance particularly on slower systems (which can have notably higher output to perf.log, further amplifying the problem). Therefore we make simulation perf logging opt-in. Additionally, logging of the current tick and tick type (local/net) is removed from debug.log, and some remnant debug logging for kills and pips is removed to keep performance-sensitive logging limited to perf.log.
