On RAM disk I run one instance of MT4 with 4 pairs and on the system drive I'm running the other MT4 instance also with 4 pairs. I have 6 years old laptop with 16 GB RAM and running Win 11 pro. Both MT4 instances are running smooth and without any lags or crashes.
The metatrader doesn't consume more than 20% CPU per instance, but always bear in mind that when you're learning, you need to add more indicators to better understand the logic and then you can really see the difference in metatrader's performance, but this only applies to low tf, such as M1/M5.
I also don't like having too many pairs open on the same account, because it also becomes very difficult to manage stress and anxiety.
