If you are thinking on trading performance, then you need to understand that it depends only on traders skills, not from broker. Broker is intermediary between you and market and nothing else. As for platform MT4 or MT5 are mostly used and quite solid platforms
There are many reasons why you should use VPS instead of a Desktop PC.Why do you even need it anyway ? Are you not doing it all from desktop PC and whant to automate some things ? If you have such a knoledge which I've seen on myfxbook.com and some other you really know which VPS to choose anyway, that's my point of view
A VPS is best for a system administrator or programmer to test or host a web site, database or power your apps that requires full customization which is usually not available in a shared hosting environment. If the traffic and work load requirement is moderate then the VPS is your answer. It costs you half the price of a dedicated server but if you care for an increasing in demand for the calculation power and storage space, then go for the cloud.What is VPS mainly used for, and why do traders mostly prefer trading with VPS?
