[issue3136] Performance of "hg status" is very bad with largefiles extension enabled

[Na'Tosha Bard]

New submission from Na'Tosha Bard <natosha at gmail.com>:

The performance of "hg status" with the largefiles extension enabled is very
bad, especially on largefiles repositories.  For our repository, if I run
"hg status" without the largefiles extension enabled or being required:

real	0m0.494s
user	0m0.390s
sys	0m0.100s

If I enable the largefiles extension:

real	0m2.230s
user	0m2.035s
sys	0m0.191s

So with the largefiles extension enabled, "hg status" is clearly about 4.5
times slower than without.

I actually have a patch for this problem that I will soon send, but I
thought it would be good to document the case here.
