I’ve got good news about the FTP performance in jSunnyreports.
I have a preliminary version with multiple threads with FTP running. I have done a test with a local FTP server I’m running. With Filezilla FTP and 2 threads I get up to 950kb/s upload. Not higher because of the small files and the overhead that brings.
When I run Jsunnreports with one FTP thread I get up to 400-450kb/s. When I increase the number of threads to 3 the FTP performance goes up to 979kb/s in my last test.
I will test the code for the coming days and will release a new alpha or beta release soon.
