Re: Accessing SMB shares extremely slow

[Martin Apel]

Hi Michael,

thanks for the patch, I tried it out. Unfortunately it does not help. 
Here are the new measurements:

tramp-smb-file-name-handler                 332 13.663383000  0.0411547680
tramp-smb-handle-file-local-copy            1 6.814127      6.814127
tramp-smb-send-command                      1 6.81183       6.81183
tramp-smb-wait-for-output                   1 6.811686      6.811686
tramp-accept-process-output                 7 6.8113620000  0.9730517142
accept-process-output                       7 0.805556      0.1150794285
tramp-smb-file-name-p                       332 0.0028720000  8.650...e-06
tramp-smb-handle-expand-file-name           97 0.0021810000  2.248...e-05
tramp-smb-handle-file-writable-p            2 0.001121      0.0005605
tramp-smb-handle-file-attributes            36 0.0010399999  2.888...e-05
tramp-smb-handle-file-directory-p           1 0.000625      0.000625
tramp-smb-get-file-entries                  1 0.000104      0.000104
tramp-smb-maybe-open-connection             1 0.000103      0.000103
tramp-smb-get-stat-capability               1 3.4e-05       3.4e-05
tramp-smb-get-localname                     1 2.9e-05       2.9e-05
tramp-smb-get-share                         2 1.300...e-05  6.500...e-06
tramp-smb-get-cifs-capabilities             1 1.3e-05       1.3e-05

I noticed, that the line numbers in the patch are significantly 
different from the ones I got. I used the tramp version delivered with 
Emacs 24.2,
so the line numbers, where I applied the patch, are 1375 and 1389. 
Should I upgrade to the most recent version of tramp and try again?

Best Regards,

Martin
