My machine is about 10 years old (Ubuntu 19.04, Intel Core2 Duo T95,
4GB). It runs today

   passed  37/47  tramp-test35-remote-path (4.826182 sec)
   passed  42/47  tramp-test41-utf8 (2.885723 sec)
   passed  17/47  tramp-test12-rename-file (1.725029 sec)
   passed  16/47  tramp-test11-copy-file (1.437843 sec)

But experience has shown, that it easily doubles or triples the time if
there are parallel tasks. It would need more debugging on your machine
in order to understand, where the time is spent.

Best regards, Michael.
