Hi Dana, Thanks a lot for your email, as you known FtpServer is a OpenSource project from the apache foundation, that I'm using in a simple application for personal use.
The thread I opened was more focused to implement such high-speed protocols in the OpenSource community, and asked feedback if anybody used them, or why none current OpenSource project tried to implement it's own. I did download ExpeDat for evaluating if your claims are accurate. I have to say I only tested ExpeDat and none of the other competitors due the facility to download the evaluation, and also because I'm linux based and your software fits here, so congrats on that side. Having this said, the test showed less performance than using plain FTP connection ( without any kind of SSL ), on a Wireless 802.11g LAN. I transferred a 700M Ubuntu ISO file a 'bit' faster using plain FTP ( 15 seconds faster). I repetead the test from my ADSL line (12Mbit) , having the remote server on a 100Mbit link located in datacenter, with 54 ms latency, and FTP file transfered 10 seconds faster as well. I made probably simple tests, or maybe your protocol has faster throughput for longer distance WAN with higher latency, more congestion networks or etc. Nevertheless thanks a lot for your email. Best regards, DevNull43.
