I presume that you mean 'renders slower' when you say 'renders not as
well'.
This case can always happen, if single-GPU local rendering is faster
than the compositing overhead.
First check if you have a release build.
In your example config you can try the following things:
1) Use a 2D instead of a DB config, since for DB decompositions both
the color and the depth buffer are used for compositing.
2) Optimize the depth-buffer compositing code. The readback and write
of depth values can still be optimized in Equalizer, for example by
using FBO readbacks
3) Optimize the image compression speed and/or compression ratio
4) By faster network hardware
If you want to pursue options 2 or 3, please get back to me, I can
give you some more information and entry points.

Equalizer does not use the ssh link for network traffic, it is only
used to launch the render clients, so this should not be related.
Btw, you don't need the empty clear compound, you can also use task
[ CLEAR ASSEMBLE ] for the top-level compound.
Cheers,
Stefan.
