The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is.

Performance Tuning of GlbalScape uploads using SSLoFTP

Asked by NDB13 in FTP Software, File Transfer Protocol (FTP), Secure Socket Layer (SSL) & HTTPS

Tags: GlobalScape, Secure FTP Server, 3.x, using SSLoverFTP

Hi All -

Just looking for some tips & tricks or advice, experiences, opinions... on tuning the GlobalScape SFTP Server for optimal upload performance when using SSL over FTP. Our SSL is a signed certificate from Thwate as opposed to a self-signed key created in GlobalScape.

I recognize that upload speed will be determined by the ISP limitations of the user doing the uploads, but I want to ensure the highest possible throughput to the server from the client. I haven't done much yet in terms of setting Max. Transfer Rate in the GlobalScape software itself.

Personally, my ADSL line can sustain around 35KB/sec of upload speed to the server hosting GlobalScape in our environment. This is from my apartment to our servers, all within the same country (only about 20km away from the servers). And 35KB/sec is what I get to other FTP sites I've tried, so no problem there.

But once in a while users will complain about very slow upload speeds, and when I look in the Server stats in the Admin. page of GlobalScape in real-time, can see their upload speed is like 6KB/sec and I even saw one guy uploading at 2Bps. I can't verify it, but these users tell me they have regular ADSL lines and theoretically they should be hitting 35KB/sec also. I have noticed a few times, when connecting to GlobalScape using the cmd prompt in Windows, that doing ftp> dir will load 1 character at a time; e.g. if the file name is test_upload.txt, then the letter "t" appears, then .5 sec later the letter "e" appears, then .5 seconds later the letter "S" appears ... normally doing ftp> dir spits out the entire directory structure in .5 seconds - but once in a while I'll do this crazy one-letter-every-half-second stint.

So I'm looking for advice or tips on how to ensure that the SSL over FTP uploads from any client will be limited only by the upload speeds of their ADSL line as opposed to a limitation on our GlobalScape settings or configuration. Or pretty much any tips on performance tuning a GlobalScape FTP server.

Thanks,
