It seems like the Box Platform auto-determines the part_size of a chunk during a chunked upload session. Is it possible to modify or specify a desired part_size ?
For a trial I did, the part_size was 8Mb when I was uploading a 50Mb file; was 16Mb for a 200Mb file and 32Mb for a 1Gb file. For the network bandwidth that I'm using, a 32Mb chunk is just too large to handle and hence requires multiple resumes of the chunked uploader. A smaller chunk size would be ideal. But I don't see a way to specify it.
"part_size" is one of the response parameters (https://developer.box.com/reference/resources/upload-session/#param-part_size) for a call to "Create upload session" (https://developer.box.com/reference/post-files-upload-sessions/)
