You have access to everything you need to customize this client from 'Option' area. The transfers from all torrents will appear on a left column close to the 'Search' feature.
You can even lock down qBittorrent with a password if you want to keep your activity private. Performance: I (and a few friends of mine) was able to reach the maximum speed provided by my ISP on Windows® 8.1 and 10 (100 Mbps). Apparently, such high-speed transfers are achievable from close locations but what I am trying to say is this: there's no limitation coming from this software.
