Extremely slow local speed when uploading large files #102

Closed KelSolaar closed 1 year ago

KelSolaar commented 1 year ago

Hello,

I'm using the component locally to upload multiple gigabytes files, e.g. 10Gb, and the performance is really extremely slow.

Given a zip file of 11.2Gb, it takes 8.5s to make a new copy of the file while the upload takes 12m11s which is almost 2 orders of magnitude slower. Before I report that to Flow.js, I was wondering if you could think of anything obvious?

Cheers,

Thomas

Allright, as I posted that I saw discussions about chunk size related performance on flow.js , I increased it and it is much much faster!
