Bernd,

Difficult to know without actually being able to reproduce. What is the 
performance of converting it to a shapefile for example with ogr2ogr ?

ogr2ogr target.shp /path/to/source.gdb

One case that I'm aware to have bad performance with the FGDB SDK is when a 
layer has hundreds of fields par feature, like with US Census files.

If you can share your database, I can also try having a look (at the OGR side 
of things)

Regards,

Even
