Slow user interface performance

[cyberduck]

bc5b38f created the issue

I've used cyberduck for a long time, both on windows and mac. I always thought the slow performance on mac was hardware issue as it is an old macbook but then i booted up a virtual machine on it with windows and installed it there. It was like day and night. Why is cyberduck on mac so unresponsive, laggy? Quick search, scrolling and directory listing is slow. Is there a solution? Also i tried cyberduck on other mac's just to be sure it wasn't just my mac.

Version 6.2.0 on El Capitan

My CPU runs at 100% while scrolling a folder listing up or down, making the interface react slowly. Should I open a new ticket, or is my issue part of this one?

Please reopen ticket. 6.3.1 scrolling is much slower, more laggy than 6.3.0. CPU usage over 100% while scrolling. El Capitan, ATI Radeon HD 5870
