actually I guess that lineoffset and filter, once compiled, use rather

Yes, that's my understanding, at least for the filter command which
drops into a rather complex regex subsystem, so while it's darn
convenient at times it almost always benchmarks slower than alternatives.
I don't understand why lineoffset is slower, however, and have submitted
a request to have it reviewed for potential optimization:

Thanks for bringing this up. As the engine gets ever more optimized,
any performance gaps between our scripts and native compiled C code get
ever smaller, allowing us to use those clock cycles saved on adding new
features in our apps.
