What are the techniques to increase the speed of bots for, for example, buying tickets?

Question

Bots

Let's say there is a website that sells football tickets. And they are dismantled very quickly, it is almost impossible to buy by hand.
What should be paid special attention to in order to increase the speed of the bot that makes these purchases? What factors will help the bot do it faster than others?
Also, does the language itself matter? I think that the role of the language is not so important here, because the main thing is to send a request. As soon as it is sent - that's it, the difference in speed between Python and C ++ ceases to matter. Right?
In general, what factors are decisive here?
Are there any good resources on the topic?
