I don't change the maxrate or blocksize properties so they are default. What could cause the much slower download in the dart software? ANd how to fix it? I'm using Dart.Ftp.Dll 4.7.2.0 Thanks!

Setting this to a greater value then 32kb (which seems to be the default) greatly improves the transfer speed. Setting it to 1024kb results in the same transfer speed as in FileZilla. I'm assuming a greater value affects the transfer speed of smaller files? Is there a way to make this a "sliding" value? ...increase it during transfer to reach optimal transfer speed? Or is it safe to simply set it to a large value like 1024kb? ...I don't want to confuse my clients by making this a configurable setting they don't know how to use. Thanks for the info!
