Convex sync suddenly slow

Hi Convex team! I'm experiencing super slow queries, mutations and dashboard page loads as of ~10-15 mins ago. Is there an incident or am I possibly getting rate limited?

By "super slow" I mean 15-60 seconds to load a new page with a query on it

Hi Charlie, what's the name of your backend?

The websocket is wss://merry-dalmatian-165.convex.cloud/api/1.2.1/sync

@charlie does your Convex dashboard show these queries as taking many seconds? Are they particularly large payloads? How slow are the dashboard page loads? We have a known issue with dashboard page loads that should not affect other deployment performance (slow cold starts from Next.js, been meaning to get to this). However if your queries and mutations are super slow there's something we're not seeing.

@ballingt It seems like it must have been intermittent as things are back to normal now In the logs, every query either says "Cached" or <100ms

Gotcha, this sounds like a network issue @charlie

That makes sense, but I was seeing 600 Mbps on fast.com so wanted to report in case it was something to do with the websocket service

We have work in progress to improve the push times by making bundles smaller, which should help with this 10.98m (!) deploy Oh that's helpful to hear, may help narrow it down.

Thanks for looking at it! I'm unblocked, will report back if I see something again
