Trados probably is one of the slowest program running on my computer.
It's ok for most translation/review and basic project management tasks.
But a lot of tasks are very slow when working with big files / lots of files, whereas CPU / RAM usage is at the lowest.
The program startup itself is very slow, slower than much heavier programs I am running. And navigating between the different sections of the program is slow as well (when you hit the Report section by mistake for instance).
I don't know if it would solve the problem but I don't understand why such a "big" program still is running in 32 bits in 2017. Being able to choose between a 32-bit and a 64-bit install would be nice.
That being said, there are some really nice additions in Studio 2017.
