[ome-users] Network drive slowness

Hi Niko,

You're probably right that the File.isHidden() in BioFormats isn't called
in the OMERO importer at the client side. However, from quickly grepping
through the source of openmicroscopy/components/insight I found several
calls to File.isHidden(). I was wondering if these are also meant to be
optimized as part of this issue.

What we experience in the OMERO importer is for very low latency network
drives that the import is relatively slow (compared to file copy). For
higher latency network drives the import is slow and the importer UI
becomes unresponsive (although the import continues). If you want me to
quantify these experiences, I could do that.

Thanks,

Paul
