I figured I’d also do the test you won’t do. These are my results for uploading and downloading a 4GB file on a 1gbps connection.
These show first uploads with parallelism set to 1, 8 and 16 respectively and then download for the same thing.
You can see that for upload it is able to utilize almost my entire connection speed with parallelism set to 8 and 16 saturates it completely.
You’ll also notice that downloads are a little different. I ran these tests on my Synology and the downloads were so fast that my measly low energy 4 core Xeon D-1527 couldn’t keep up.
Keep in mind that this network usage represents traffic of erasure encoded pieces and thus effective transfer speeds of the actual files is lower. For upload there is an expansion factor of about 2.8x and for download about 1.5x. I’m limited by my network connection here. This could go much faster on faster connections.
All these tests did was expose my own bottlenecks, not Storj’s. Hope that helps.
