Hi,
My desktop is the "Workstation Edition" and I use the files menu with copy and 
paste. In the case of interest (F26) the first 1.5 GB are copied very quickly 
(about 100MB/sec) then the copying process slows down to about 11MB/sec. After 
signalling completion I have to wait about 4 minutes untill I am allowed to 
eject. If this is normal, then OK, if not, possibly I should file a bug.
Kind regards

Ok, then it used to be standard behaviour and I haven't paid attention 
to it since then. :-)  I will have to try it out, but I thought I saw 
this with nautilus recently._______________________________________________test
