A download utility to test throughput and duration that leverages configurable, concurrent, multipart downloads.
foldspace <url> <chunk-size-bytes> <max-parallel-requests>
For example, to download $URL
in 5 MB chunks allowing up to 12 parallel requests:
foldspace $URL 5000000 12
NOTE: this program does not save the data it downloads, but pipes it to /dev/null.
