Hi Michael,

I tried this, but it didn't have any effect. Any other idea?

Best Regards,

Hi there,
Hi Martin,

I tried to investigate the cause for this and found out, that most of
the time is spent inside tramp-accept-process-output as can be seen
from the following profiling output for a single file open:

tramp-smb-file-name-handler                 330 13.859976999 0.0419999303
tramp-smb-handle-file-local-copy            1 6.914245     6.914245
tramp-smb-send-command                      1 6.91259      6.91259
tramp-smb-wait-for-output                   1 6.912537     6.912537
tramp-accept-process-output                 7 6.9121980000 0.9874568571
accept-process-output                       7 0.903607     0.1290867142
Wow. The major functionality of `tramp-accept-process-output' is to call
`accept-process-output', they shall have similar timings.

What happens, if you remove the `with-timeout' form around

Best regards, Michael.
