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.

FITS on Github

A fork of FITS is now up on Github. Let me know if you want to be added as a contributor.

The JHOVE 1.8 jars are now there.

Optimization tip

The HTML module in JHOVE is very slow and not very useful unless you're rejecting the 90% of the HTML files that aren't strictly valid. If you don't need it, edit xml/jhove/jhove.conf and remove the module element which refers to edu.harvard.hul.ois.jhove.module.HtmlModule .
