eog is horribly slow in any directory with more than a few hundred images. with 10,000 plus images it usually just crashes. by default it tries to preload EVERY image in the directory.
irfanview is orders of magnitude faster. pornview works well too, but doesn't seem to be maintained.

If the working with EOG seems inconvenient to you, please file a bug report against EOG for this issue or direct your suggestion to the EOG developers http://projects.gnome.org/eog/
