            Bug ID: 1049
           Summary: saving ROIs on a network drive is slow
           Product: Fiji
           Version: unspecified
          Hardware: PC
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P4
         Component: Plugins

Saving a ROI set from the ROI Manager to a windows network drive is slow.

For example 1700 square ROIs (about 270 kB RoiSet.zip file size):
 - saves in less than blink of an eye on local hard drive
 - saves in about 5 seconds on cheapest USB 2.0 FLASH drive
 - saves in about 100 seconds on Windows Network drive (1 GBit link, 60 MByte/s
bulk read, 100 MByte/s bulk write).

For comparison, compressing 1700 individual ROI files with Total Commander:
 - takes less than a second when the destination is a local drive
 - takes about 5 seconds  when the destination is a Windows network drive.

Still, ImageJ is unnecessarily slow...
