SFTP Upload Speed

Question

Hi.

I am trying to figure out which parmeters influence the upload speed for a SFTP-connection. I setup a second remote server for my data. My max. line upload speed is 40MBit/s the remote line download speed is 200MBit/s. Currently the maximum speed I get uploading data is around 12MBit/s. I have validated that speed in the Windows Task Manager.

In the I/O Manager I have set no throttling and 5 download and upload threads. Maximum connections is set to 10. My cache drive is a 50GB partition on a SSD. Upload verification is set to True.

Do you have any hints or suggestions

For the upload speed, how much data do you have "to upload".  It this is a small amount, that may be why, as we do some optimization that delays writes, to prevent re-uploading the same chunks repeatedly if it's being modified frequently. 

Otherwise,.... create a new drive and use larger storage chunk size (this setting can ONLY be configured when creating the drive).

Hi Christopher.

It's about 1.5TB of data mostly Photos and Videos with file sizes of about 20MB and a bunch of documents with quite small sizes. I have used the standard chunk size or did not change any setting during setup. So which settings do you recommend?
