As Jurgen has commented on the pull request already, we have figured out that QGIS was taking a lot more time to access features from a local PostgreSQL database compared to some other app (uDig?). I have dug out an old mail with the measurement - the difference was ~12 seconds to fetch data in QGIS vs ~4 seconds to fetch data in the other app. In the end we figured out that disabling encryption removed that penalization. All that was back in 2009 :-) Unless there have been some improvements in the server/client lib, I think the promise of massive speed up is still valid... And as Andreas mentions, most(?) of the time people use the DB on a local network, so it should not be a big deal to send data on local network unencrypted.
