Limit number of parallel uploads

Is it possible to set max number of files that are uploading simultaneously. Right now it is 12 on my laptop

I have a lot of large files (50GB+), and when 12 of those files are uploading it takes forever to upload them all, and if connection breaks for some reason, they all start uploading from zero, its really annoying.

If it is not currently possible, would you consider adding this feature in the future.



This would be a welcome improvement.

I’m having the exact same problem as the original poster, the uploads take forever and sometimes the connection breaks and they have to start again. For some files this has happened several times now. I’m reaching the point where I’m going to have to complete my uploads via the web browser interface, which defeats the point of having paid for InSync. I looked in vain for an option to configure the number of parallel uploads, it seems to me an obvious feature, but I note other threads here going back years with no action taken to make this an option. Surely it can’t be that difficult to add? I would much prefer to have a smaller number of files transferring more quickly.

Further update, I’ve given up trying to get my large files to sync when copied in all at once, copying them into the synced folder one at a time is working and getting them onto OneDrive. Having spent literally an entire day trying persuade the last batch of files to sync when all were copied in at once, removing them from the folder and copying them back in one at a time is givng upload speeds that will probably allow me to complete the task in about an hour. So the ability to limit the number of simultaneous uploads is critical if you work with large files.

Also, looking around the forums I see that this was promised as a feature for v2 of Insync in 2016. Where did it go.

Furthermore, I have found that if I pause the large uploads for an hour or two because I need the bandwidth for work, they frequently re-start from 0. Again, if less were uploading at once, this would be far less of an issue.

Sorry for the rant, but feeling a bit short-changed at the moment having recently purchased InSync only to have it fall over this badly the first time I try to use it anger, when a seemingly simple feature that ought to have been there from the start would solve the problem.

Hi @tim1mw,

I apologize for the trouble you’ve experienced with a large upload and I understand your sentiments about your experience. We would like to look into the cause of the slow sync and what’s causing the bottleneck in your sync progress.

Please send your logs with the link to this post and include the following files in the folder:

  • logs.db
  • out.txt
  • data folder
  • live folder

If these are too big for an attachment, feel free to send us a link so we can download these.

Hi @miamoran, I’m not @tim1mw but wanted to clarify - at least in my view - that the slow syncing isn’t due to a bug in Insync. It seems to actually be a feature, and related to the change made in v3 that uploads 12 files at once as @pedja1 mentioned in the OP.

The upload speed of most people’s internet connections is only a fraction of their download speeds, which usually results in 10Mbps/sec uploads or less. Then split that small amount of bandwidth over 12 large files at once, and it’s more likely that the file times out or the user has to shut down their computer or put it to sleep before the file uploads. And every time I’ve had to do that in the past, Insync v3 will start the upload over again.

The only way I was able to get my 100gb file to upload was to change my power settings so that my computer never went to sleep until the file was uploaded. Not an optimal scenario.

In my opinion, 2 things need to be fixed:

  1. Reduce the number of simultaneous downloads (whatever Insync 1.X was set at seemed to work well for me)

  2. Have Insync resume syncing a file if the computer gets shut down or put to sleep instead of starting over again. Insync 1.X seemed to do this well enough.

Thank you for your feedback, @moeschl. I appreciate it! Let me forward this to our engineers so we can work to improve Insync’s sync speed and performance. We initially deployed the feature to sync 12 files at a time to reduce the CPU consumption but it does seem like it also affected the overall speed, which we will look into further. :slight_smile:

This would be a very helpful feature. I spend the whole day with InSyncq turned off because of it.

The OS is MacOS Catalina
