core.bigFileThreshold
Files larger than this size are stored deflated, without
attempting delta compression. Storing large files without
delta compression avoids excessive memory usage, at the
slight expense of increased disk usage.
Default is 512 MiB on all platforms.
This should be reasonable for most projects as source code and other
text files can still be delta compressed,
but larger binary media files won't be.
Common unit suffixes of 'k', 'm', or 'g' are supported
