[QGIS-Developer] SSL Performance Overhead

[Matthias Kuhn]

Hi,

The documentation currently promises "massive speed-ups in PostGIS layer 
rendering" with SSL disabled. [1]

I find some references to performance cost of SSL but they should be 
compensated for with connection pooling which we use for quite some time 
already.

Recently, the web is more and more encrypted - and that is very good! - 
so I think we should also start to encourage people to encrypt their SSL 
connections. Or at least certainly not discourage them from using 
encryption by promising performance benefits.

Is there anyone who knows why this sentence was introduced? And if there 
is (still) an issue with performance when using SSL?

Best regards

Matthias
