The technical nitty gritty

GGST makes a new TCP connection and a new TLS connection every API call it makes. And it makes hundreds of them in the title screen.

Totsugeki solves this by proxying all API requests through a keepalive connection.

What this means is instead of doing 4 round trips (TCP + TLS + HTTP) for each API call, it only needs to do 1 (HTTP only). This shortens the loading time by a factor of FOUR! For example, if you live in the EU and have ~300ms ping to the GGST servers, you usually see something like 300ms * (1 TCP round trip * 2 TLS round trips + 1 HTTP Request round trip) = 1.2 seconds per API call.

This multiplied across all 127 API calls needed to get to the main menu means it takes a whopping 152 seconds (2.5 minutes) to load into GGST.

With Totsugeki, this is brought down to a mere 38 seconds.

This has added bonus of reducing GGST server load, as TLS negotiation is one of the most CPU intensive tasks today.

Thanks to u/TarballX for doing the initial research on why GGST takes so long to connect.
