I’m using a GE865-QUAD and was using HTTP through the AT commands with slow but reasonable performance. We switched to HTTPS and the performance is abysmal… it takes a long time (20+ seconds) to establish a connection and transfer just a few bytes of text with a site that has a valid SSL certificate. Is this performance normal from the HTTPS stack?
Also, does using TCP directly improve the performance over HTTP? It just seems like the stack is slow.
What HTTPS stack? You mean SSL connections over TCP sockets?
Yes sorry, was confusing something else… just creating TCP socket connections on port 80 and 443 when SSL, following the guide.
You can give a try with AT#CPUMODE=1.
