This page is for notes on how to optimize FITS.

Thread parallelism and memory consumption

FITS runs all its tools in parallel threads. This can result in heavy memory consumption, particularly if a big file is being processed. Harvard optimized FITS for DRS ingest, which can afford a lot of memory. In other environments this might cause thrashing.

One approach might be to add a command line or config parameter to limit the number of simultaneous threads.
