Basic internet math for @elonmusk's claim load time in India is 20s because of 1200 RPC calls (v.s. 2s in US):
Bangalore->SF is ~250ms
1200 *.25s = 5 minutes! Way off!!
20s load time = MAX of 80 sequential calls
Reality is likely 5-10?
1200 is happing inside datacenter?
Elon Musk@elonmusk· Nov 14, 2022@sampullara I was told ~1200 RPCs independently by several engineers at Twitter, which matches # of microservices. The ex-employee is wrong.
Same app in US takes ~2 secs to refresh (too long), but ~20 secs in India, due to bad batching/verbose comms. Actually useful data transferred is low.

Twitter is very slow in India, Indonesia & many other countries. This is fact, not “claim”.
10 to 15 secs to refresh homeline tweets is common. Sometimes, it doesn’t work at all, especially on Android phones.
Only question is how much delay is due to bandwidth/latency/app.
