[Qgis-developer] Postgis-Provider and compression

[Andreas Neumann]

Hi all,

I wonder if the current Postgis-Provider somehow supports or would support
compression during data-transfer between the QGIS-client and the remote
Postgis-server. In my experience, data transfer across slower connection
(DSL, cable) is often rather slow.

Would there be, technically, a way to accelerate data transfer over slower
network connections?

I also remember that Sandro Santilli once suggested a keyword substitution
parameter for the psql provider so one could use simplify based on map
resolution/map scale. This should also help to speed up data transfer on
slower connections

unfortunately noone answered to his mail. I think the proposal would be
interesting to follow.

Andreas
