Summary0009207: QR code generation reported as 'too slow'
DescriptionAt the Dresden bar (using an old tablet and possibly not-so-great Internet) the bar staff mentioned that the QR code generation took ~4s which was perceived as slow.

Suggestions:
1) maybe try to keep-alive the TLS session, so we avoid the handshake for every HTTP request. TLS keep-alive, maybe need to configure curl, maybe requires server-side setup;
2) do the order creation *before* the user hits "complete", and delete the (optimistically) created order(s) on update (when staff modifies an existing order).

That way, the network latency can be possibly completely hidden by the human delay between pressing buttons and the QR code can be shown instantly.
TagsNo tags attached.

This seems stale, there are no concrete numbers to justify optimistic order creation.
