Hi, I have been contacted by a handful of people who use my auto speed tester app who are having trouble with the upload speed testing. It seems that anyone with a faster than 2 to 4 Mb/s upload speed is showing that there is a discrepancy between the AI FTP upload commands and other FTP clients. If i do a bog standard _FTP_FilePut() with AI the max throughput it gets is approx 3Mb/s but when i upload the same local file to the same server with filezilla it gets a throughput of over 14M
