Page load time in 1.8.2

Having upgraded from 1.8.1 to 1.8.2, the page load times have increased from almost instant to about 10 seconds. This is when developing, and after Meteor has performed a client refresh.

Has anyone else experienced this problem, or can suggest a solution?


Hi, can you open an issue here

Also if you could provide a reproduction it would be very useful as we have many projects already running on 1.8.2 without this issue.


I assume you are actually talking about page load times and not the refresh / rebuild -time.

I’ve experienced a similar glitch 7-10 times, aka very rarely since I work with Meteor on a daily basis.

The server just becomes extremely slow to response. It can take 10-20 seconds for the first requests to be handled (from localhost!).

A simple restart always fixes the problem.

Sorry for the delayed reply. I tried the update again now that 1.8.3 has been released, but still stuffer the same issue. It’s definitely the page load time rather than the rebuild time.

I’ve tried serval restarts, meteor resets, and clearing chrome cache, but to no avail.

We have quite a large project, so it’s hard to figure out where to start with debugging this issue.

I’ve been trying to dig a little deeper and can see in Chrome’s performance monitoring that it’s the moduleLink function that is causing the slowdown (see below). This takes around 1s on 1.8.1, but takes >8s on v1.8.2 and higher (inc. v1.9).

It happens both in dev and on a build.

Unfortunately I’m out of my depth in terms of debugging this, so any help would be greatly appreciated.

Half of the mystery has been solved: It was the use of destructing on the mdi-material-ui package imports that was causing the problem.

The part the remains unsolved is understanding what changed between 1.8.1 and 1.8.2 to cause this issue in the first place.


I’ve got exactly the same problem. In 1.8.1 it’s loaded immediately and in 1.8.2 or higher it takes like 2 minutes. Also got a large project. Let me know what else you find out

Nevermind, for me this fixed it.
