Re: Accessing SMB shares extremely slow

[Martin Apel]

Hi Michael,

I downloaded Tramp 2.2.6 and compiled it locally, once with and once 
without your patch.
Unfortunately it still takes long to load a file via SMB, although the 
numbers have changed a bit.
These are the timings with your patch applied:
