Comment:
  Unless you do have these 500 files on the repo root, we don't even access 
them. First, we check from outside if there is a a .hg dir inside a directory. 
If there is, we then look for a file .hg/thgstatus.

Only if you open the repo root, we read the file .hg/dirstate (which is 
ridiculously small for a 500 files repo) and then we do a stat call (asking for 
the file size and modification times) for every file on the top level of the 
repo root. Files inside subdirectories aren't even looked at -- unless you 
navigate into a subdir.

Such huge times are unlikely to be explained with network latencies. Rather, 
there must be some protocol round-trip timeout involved.

Windows 7 introduced some new kinds of networking. Maybe there is some 
misconfiguration involved here as well?

It's hard to tell how relevant this bug here for TortoiseHg really is, as it 
affects only the combination Win XP accessing a share on Win 7 RC (which is not 
even a released product, so hardly anybody would use that as a server now).

How fast is opening a larger file (>10MB) residing on the Win7 share from Win 
XP (with TortoiseHg overlays  turned turned off)? For example a Word document?
