I am running 2 Intel NUCs 24/7 to forward testing different stategies with some MT4 instances running at same time. basically i had no issues for ages. I know how to change numbers of bars on history and/or charts in settings to avoid any slowdowns, also i reboot both NUCs sometimes to clear cache ....

Since start of May when WIN10 updates came out, i noticed on both NUCs that basically the CPU-load is higher than before, approx. 10-20% more.
therefore i had to close some open MT4 instance to avoid CPU running almost straight with 100% load in open markets times (before the WIN10 updates this happend rare and only in very heavy price actions on markets..)

as I said before reduce bars in history and/or on charts in settings does not help....
Who have the same issue or is it only on my side?
Thanks

Ctrl + Shift + Esc to bring up Task Manager and check what is using most CPU.

Also consider shutting down all the background apps that sit there running in case you might want them but usually never do (just means they take a bit longer to start up if you do activate one).
