ZwiftPower has been struggling to adequately process rider metrics and fit files for the past few weeks as Zwift usage has soared to unprecedented levels. The backlog had been growing continuously, with the pending metrics exceeding 100k and fit files exceeding 150k as of a few days ago.
This impacted racers in a variety of ways including delaying category upgrades, displaying inaccurate data, and preventing the viewing of specific power numbers for an event.
Inconveniently, the Zwift devs responsible for ZwiftPower were away on holidays when this problem got ugly, which slowed down the implementation of a solution. And concern was growing with Zwift Racing League Season 2 launching on Tuesday, since this will be Zwift’s biggest race series to date!
But here’s some good news for your Friday: I’ve just been informed that today, the problem has been fixed (see the Zwift forum thread.) Where ZwiftPower was previously limited to processing one file at a time, it is now multithreaded and able to process at least 200 per minute according to one source. (It looks to be moving even faster, from what I can see: closer to 300 per minute.)
Will this be enough? It’s certainly an improvement. Time will quickly tell if processing needs to be further boosted.
ZwiftPower’s backlog problem didn’t have a quick fix, from what I’ve heard – it required coding changes on ZwiftPower’s side plus changes to Zwift’s API which is used to grab the files.
Even as I’ve composed this quick post, the backlog of pending metrics and fit files has been shrinking. Here’s where the numbers currently stand:
At 200/minute, those numbers should be at zero by 4:00pm Pacific time. We’ll keep an eye on it and see what happens!
Kudos to Zwift devs for getting the problem resolved. We like to give a little guff to Zwift for moving too slowly or not implementing the features we want, but I think it’s always a good idea to give a thumbs up when it’s due.
That current number of fit files in the picture is either very coincidental, or a bug… 65,535 is (2^16 – 1), which is a common value in computer science for overflow or invalid value (it also happens to be “-1” when represented as an unsigned number, but now I’m getting pretty technical).
Just a coincidence! Shows 63,766 now.
Glad this has been fixed, although the power data that has pulled through has bumped me up to Cat B! 😢🥵
Congrats!
Congrats!!
LOL. I feel your pain. I got bumped up last summer and it was less than optimal for me. It’s way more fun to be at the pointy end of the peloton than in the grupetto…
Kudos to Zwift for taking over Zwift Power over the summer, ruining it, not caring, and finally fixing it! You deserve a lot of credit Zwift! Remember when real peak zwift was hit last year and this didn’t happen lol?
ZwiftPower wasn’t processing files any faster last year, it’s just that total usage wasn’t as high when April’s peak zwift happened. The number of ZwiftPower users was much lower, and the number of event participants was much lower.
Not excusing Zwift’s lack of attention to improving ZwiftPower and/or their racing tools, of course. Plenty of room for improvement there.
200/min? What hardware are they using? C64? At least they heard from multithreading 😉
“Where ZwiftPower was previously limited to processing one file at a time, it is now multithreaded and able to process at least 200 per minute according to one source.” Exactly what I was thinking. Should we all be happy now that they upgraded to technology used in similar situations 20 years ago? At least Eric was nice enough to give us a little info in this article … It is more than Zwift did.
It’s definitely shrunk significantly. They’ve already processed the file for ny WTRL TTT last night.
The 3R race from this morning is also already processed! Happy to see this!
I wasn’t in a hurry to get upgraded anyway…..:)
The number of .fit files to process is at zero currently. Yay.
Just saw that. Excellent!
Cannot be, I am still waiting for Dec. 26th….
That’s how it is displayed, but the actual backlog at the moment is still 3–4 hours worth of race data.
Zwiftpower was doomed the moment Zwift took control of the site.
As of this morning, Monday, 11Jan, 8am PST it’s completely off the rails. The events aren’t even showing up on users profile page and the event pages only have the start lists of riders that signed up on Zwift at least a day early. SNAFU…
I have 6 races since 10/18/2020 including the start of ZRL season one which are still green (live data) with no race ranking impact. Is there a way to upload my fit file to Zwift or Zwiftpower from each race to replace the live data status and see my race ranking move?
