Twitter's high ROI engineering work

funny how the argument that Elon knows nothing by bringing up RPCs is backed by (in part) a trace diagram showing RPC's all over the place.

slow clap

These people are really good at “dunking on you” on Twitter

Upon closer inspection, they’re full of s*t

> Elon knows nothing by bringing up RPCs

As best I understand the Twitter spat, he was claiming the client was making 1000 RPCs to generate the home timeline - hence it being slower in India where mobile internet is slower. Except the Android dev pointed out it was actually only 6 (IIRC) calls from the client and slowness had nothing to do with that.

Didn't Elon clarify that he's referring to the RPCs between services in the BE?

So there is a specific BE only for a region that is slow but another that is not?

Possible he did, I suppose, but I never saw it in any of the recaps / threads. But also wouldn't make a lick of sense talking about India vs US for speed...
