Is there any upload speed throttling built in to the TMagFTP
component (or Overbyte one) ?
All ICS components have optional bandwidth limiting, it's part of
WSocket, on the XferDemo3 it's set by the Bandwidth Limit field which
should generally be zero.
I have this in my code (I think lifted from your example)
bandwidth := 0;
if bandwidth > 0 then
begin
BandwidthLimit := bandwidth * KBYTE;
Options := Options + [ftpBandwidthControl];
end
else
Options := Options - [ftpBandwidthControl];
I do know from experience that ICS does not offer the maximum possible
transfer speed under Windows that is available with a blocking file
transfer API (we don't use), but that does handle SSL or reporting
(without using threads).
Presumably though that would be a small percentage, rather than a 6 fold
decrease ?
Upload OK: magtelecom.zip, size: 75.8 Mbytes, duration 0:36, average
speed 2.09M/sec
That's more like the kind of speed I was expecting here.
Speedtest.net shows an upload speed of 14.59Mbps,
FlashFxp shows upload 565K bytes/s,
MagFTP shows upload 90K bytes/s
Customers are reporting the same issue, so it's not specific to my
connection. Not sure what else to do to try and diagnose.
