This change resolves /issues/54
The code in
tab_upload.pyreads uploaded files 1024 bytes at a time. This is not efficient for large files on modern systems.UploadFile.read()maps toRawIOBase.read()which handles multiple reads to a stream internally. Documentation is available here.This change delegates stream io to the lower levels of the runtime.
