Core FTP

The only difference I can spot between the two connections is the use of SSL for the server I'm connecting to. Is there a default speed difference in using an SSL connection versus not using SSL?

Thanks to Brendon K, I was able to run the test. The test confirms the problem is NOT with CoreFTP, I just got upload speeds at 75K with his server. So I will focus on what is wrong/different with the server I'm using and how it is working with CoreFTP vs other FTP programs.

Out of curiosity, have you uploaded LARGE files for these tests? Yes, it's about the only way I can accurately gauge the performance comparision between the various FTP programs. Large file sizes range from about 9 MB up to about 25 MB. Also, if you're not already using the v2.0 series, try using t...

Are you sure you weren't confusing download rates with upload rates? The 100-150 KB/s would be right in line on downloads for your connection. Yup, quite sure. Like I mentioned earlier, sometimes the slowest speed is 75K (which is probably normal if my upload speed tests around 750 Mbps) for upload...

Wow, that's a neat test! Anyway, my results were:

1291 kbps Download Speed
742 kbps Upload Speed

I have a 1.5 Mbs DSL connection, so it's definately capable of speeds greater than 45K.

Windows SSL didn't seem to make any difference. Likewise with the ANSI version, still only get about 40-45K maximum. It's almost like there's just something holding it back from performing up to speed. Other FTP programs seem to even retrieve server comments a lot faster. Maybe I'm doing something w...

I tried changing those settings as suggested, no change in performance. It still peaks out at 44-45K maximum. I don't think SFTP is used with any of the sites I'm working with, only SSL. Any other possible options? The slowest speed I've ever encountered with another FTP program was about 75K, with ...

Is there a way to improve the upload/transfer speed with Core FTP? I have tried to change the buffer sizes and other settings with no luck. I can't seem to exceed about 45-50 KB/s no matter what I try. Oddly, other FTP programs can upload 2-3 times as fast (100-150 KB/s)... connecting to exactly the...
