Not at all, telegram clients in every platform are much much faster than whatsapp, signal etc. on the same platform. Although, this is more visible on older devices and on poor network conditions, I clearly see a difference in my newer devices too.

Could you give me one for Android which is really fast? I'd try that out on a phone with whatsapp and signal.

Also, what does "fast" mean? Fast on start?
