08/04/2021, 9:15 AMDoes anyone have numbers on roundtrip time to Durable Objects living on the other side of the world? - k
Kuririn
08/04/2021, 1:50 PMwhat is the difference between idFromName() and idFromString() and how long value (max. length) I could put there? - k
kenton

specifically parses the output ofidFromString()
. It won't work with any string that wasn't specifically created by stringifying an ID from the same namespace.id.toString()
takes any string you want and returns a unique ID corresponding to it.idFromName() - k
kenton
08/04/2021, 1:56 PMin retrospect, the naming could have been better. - k

08/04/2021, 2:05 PMthanks! - a

08/04/2021, 3:48 PMLAX to KIX is ~ 130 ms, LAX to FRA ~170 Where are you? I can send you a link to try - a
albert
08/04/2021, 3:52 PMI'm in Denmark, so I hit CPH by default. Though, due to VPN on my PC, I mostly connect to AMS. - a
albert
08/04/2021, 3:54 PMMy latency to CPH is ~10 ms and AMS is ~25 ms. - v
Vanessa🦩
08/04/2021, 3:59 PMTry these for latency testing:

Vanessa🦩
08/04/2021, 4:04 PMLooks like your VPN is slowing down things maybe? FRA should be a lot less. - a
albert
08/04/2021, 4:05 PMOh, I'm on a mobile connection right now - that's definitely why. Will test it in ~30 min when I'm home 🙂 - v
Vanessa🦩
08/04/2021, 4:05 PMOh that is a problem too of course. In LA I sometimes get single digit latencies 😍 (on fibre at home) - a
albert
08/04/2021, 4:06 PM> on fibre at home I "only" have 1000/500 over COAX (DOCSIS 3.1) :/ - a
albert
08/04/2021, 4:07 PMSpeeds are great, but latency doesn't get lower than ~10 ms to anywhere - a
albert
08/04/2021, 4:15 PM@User I launched the links on my PC now (with VPN) - v
Vanessa🦩
08/04/2021, 4:16 PMSo that's the connection from Amsterdam then - can you try without VPN? 50 ms to FRA still seems like a lot - a
albert
08/04/2021, 4:18 PMDone 🙂 - v
Vanessa🦩
08/04/2021, 4:18 PM32ms, that looks better - a
albert
08/04/2021, 4:19 PMSo 32 ms is roundtime from my PC to FRA via CPH? - v
Vanessa🦩
08/04/2021, 4:20 PMyes - v
Vanessa🦩
08/04/2021, 4:20 PMthe worker is in CPH and the DO in FRA - a
albert
08/04/2021, 4:22 PMDoesn't 50 ms seem seem alright then, if it's from my PC -> Amsterdam (VPN) -> CPH (Worker) -> FRA (DO)? - v
Vanessa🦩
08/04/2021, 4:25 PMI guess it is – I am spoiled by having the worker right here next to me 😅 - a
albert
08/04/2021, 4:26 PMI don't think there's anything to do about the ~10 ms latency added just to get out of the house 😛 - a
albert
08/04/2021, 4:26 PMthis is COAX after all - a
albert
08/04/2021, 4:28 PMAnyways, thanks a lot for the help 🙂 - v
Vanessa🦩
08/04/2021, 4:28 PMYou're welcome 😊 - v
Vanessa🦩
08/04/2021, 4:49 PMJust to correct this - your connection from Amsterdam did not go via CPH. There is a colo in AMS, so that’s where the worker was.
