Slow file uploading after meteor upgrade

[valerymagadeeva]

Hello! I updated my meteor application to meteor 2.7 (and meteor-files to 2.3.0) and as a result I have a strange issue - the file uploading takes too long time, it uploads extremely slow. (the difference between the old version and the new one is about 30 seconds for 40mb file).
I tried to use both of DDP and HTTP transports and nothing helps. I noticed that when I used HTTP to upload files the meteor server response took at least a second for every chunk. So I guess the problem is somewhere between the client side and the server side.
To upload file from client i use insert() method with chunkSize equals to "dynamic" value. The server side code is the FilesCollection constructor:

const Uploads = new FilesCollection({
    collectionName: 'preupload',
    allowClientCode: false,
    debug: false,
    protected: true,
    onBeforeUpload(file) {},
    onAfterUpload(uploadedFile) {}
})

• Meteor-Files version - 2.3.0;
• Meteor version - 2.7;
• Browser/OS - Google Chrome/MacOS;
• Seems like that might be server side issue;

Client logs:

Thank you in advance!

Hello @valerymagadeeva ,

Please update your OP following our ISSUE_TEMPLATE. And post logs with debug enabled

[valerymagadeeva]

@dr-dimitru updated!

[dr-dimitru]

@valerymagadeeva thanks, let's start with question:

1. Why you upload ccsetup592.bin but file saved as ZIP (sQW9M6qt4WaLbzefJ.zip)?

[valerymagadeeva]

The file's full name is ccsetup592.bin (1).zip - it's zip archive and it should have such extension. Anyway I tried to upload a binary file - the result is the same

[dr-dimitru]

@valerymagadeeva Do you zip the file during or after upload?

[dr-dimitru]

@valerymagadeeva to make sure this isn't caused your development environment please download, launch locally, and test uploads via this app (runs on the latest meteor and meteor-files)

[valerymagadeeva]

@dr-dimitru I unzip the file after uploading in the other part of our system. The problem is not connected to zip file. I tried your demo app and got the same result

[dr-dimitru]

@valerymagadeeva do you get a good speed when uploading at files.veliov.com ?

[valerymagadeeva]

@dr-dimitru nope, almost the same result (maybe 10 seconds faster). While in the old version of meteor I have uploaded the file for 45-50 seconds (vs 1m 20 - 1m30 seconds in your demo and my app with the new version of meteor)

[dr-dimitru]

@valerymagadeeva loads very local, any other device to test on?

I'm getting 10MB/s, which is above my upload speed test

[valerymagadeeva]

I have lower speed when trying to upload via your demo app. But my internet speed is higher

[dr-dimitru]

1. But you're saying speed was higher before last update? Including on demo website?
2. What speed do you have locally?

[valerymagadeeva]

1. idk if the speed was higher on your demo website. Now i have two git branches with file uploading - the first one with old Meteor version (1.11 unfortunately and the file is uploading for 40-50 seconds) and the second one with the new version.
2. What do you mean under local speed? My hard drive write speed?

[dr-dimitru]

TLTD; we need clear reproduction steps in order to identify an issue

[valerymagadeeva]

What info can i provide you?

[dr-dimitru]

@valerymagadeeva can not come up with something specific, as I'm not sure how to localize your issue

[valerymagadeeva]

@dr-dimitru ok, I'll try to provide something specific to reproduce the issue. But it seems I have a poor upload speed (according to the information from the demo app). Idk why and im sure it's not connected to my internet or something

[dr-dimitru]

Does anyone else experiencing this? Or have ever experienced?
