How much faster is MT5?

[Valetax]

I am getting further into building dash boards that iterate through several custom indicators. This is naturally very taxing on MT4. I have heard that MT5 is faster and accesses more cores in your computer's processer. I will admit, I have a loose idea why that is beneficial, but do not know if that applies to what I am looking to do.

The average dashboard I build that checks logic behind custom indicators will push the MT4 client to 20%+ cpu usage.

Will MT5 load dashboards that go through all pairs and timeframes (essentially iterating numerous times through arrays by pair and timeframe), check numerous indicator statuses, etc. and apply conditional OBJPROPs faster than MT4 will, ideally without freezing? Or is this simply a process that is inherently slow and will freeze any client terminal?

Yes, MT5 is better suited for your dashboards. It uses multiple CPU cores and 64-bit architecture, making it faster and more stable than MT4—especially when handling many symbols, timeframes, and indicator logic. While it won’t eliminate lag entirely, it will reduce freezing and improve performance noticeably. For even better results, consider optimizing your code or using OnTimer() instead of OnTick() to control how often your logic runs. If MT4 is maxing out, switching to MT5 is a smart move.
