There was a discussion regarding this sort of things a year,2,3... ago
and even a bug filed and closed. But I can't find the bug report now.
Maybe someone could restore it from the old bugzilla backups if deemed
In the end it was decided that WFS was developed to handle such things
but that WFS provided no means of compressing the data during the
transfer and effectively bloated the data. I think a few people briefly
looked into setting up apache to compress the XML stream to send it
across the wire but the problem was that the data was not compressed on
the fly, it was more like compress->transmit->decompress (whole WFS
result), not in chunks.
