sshfs/dolphin profiling

[Albert Vaca]

Hello Yuri,

Nice data you collected here! I think that we should, at least, ask in the
dolphin mailing list why is this happening even whith the previews
disabled. Even though they may need all these calls to check file sizes,
modification dates, etc. this should not freeze the browser at all (or it
could simply be disabled for remote file systems). Can you contact them or
should I?

Regards,
Albert
