Re: [GSoC] Designing a faster index format - Progress report week 13

Junio's index-v4 was a speed boost mainly because it cuts down on the
size of the index.  Do we want to throw that out?

That's pretty much orthogonal, isn't it?

The index-v4 is merely to show how a stupid prefix compression of
pathnames without nothing else would reduce the file size and I/O
cost, in order to set the bar for anything more clever than that.

I thought that this discussion is about keeping, squishing, or
discarding part of the cached stat info, and nobody is suggesting
what to do with the prefix compression of pathnames.
