Cannot run many instances of MT4 terminal :(

windows 10 or windows 11, two or three terminals are ok, but then more i add the more lagging i get,

page faults, handles, etc,

what to do?

1 terminal is using only 1% of CPU

why can’t I run many mt4 instances?

How did you install each terminal? How many ram do you have?

r9 5950x
128 gb ram

windows 11

i am running 13 MT4s and cpu usage is max 10% and only 8 GB is used

all mt4s are with /portable command line
everything is working, but lag is horrific for no apparent reason, no too many handles, no page faults

:frowning: win 11 is completely unresponsive

no IO to disk

Ok, did you installed each terminal to separate folder?

yes, 100%, and I really love /portable key
works like charm, but MT4 terminals are reeeally slowing everything down
in each terminal i have from 10 to 30 windows/charts

is MT5 better ? true x64?
can I run ~30 MT5s ?

where is that bottleneck in MT4s ?
it is not CPU, not RAM, not DISK IO… so why win 10 or win11 are unresponsive, and MT4s are not updating charts?

6TB NVMe SSD
hetzner servers 10GBit german network

Those are some hefty specs

Maybe it could be the way MT4 is coded or something

I am using only MT4 , each terminal with max 10 strategies because of low sending channels, MT5 has same numbers. Minimize all charts and don’t install indicators on charts, you don’t need it. Is MT5 better in this case? I don’t think so. Remember that meta terminal’s has been created for windows, if you want to use it on Linux , you have to use other software like wine, but it will be unstable.

really looks like it culprit is MT4, but they are all separated and with /portable key

cpu usage is very low for each mt4, 1% cpu max,
14 MT4 terminals
each mt4 has from 10 to 30 charts with expert adviser in each chart

by chart is mean H4 window eg GBPJPY h4 window

there are 0 indicators on each h4 window chart
pure chart window + expert

so about 300 experts in total on 14 MT4s

host linux ubuntu 22.04
guest qemu kvm win11 or win10
guest vmware 17 pro win11 or win10
same problems
even if win10 multi user is used
identical lag and stag

Did you hide unused quotes in terminals?

Hey this is a brilliant idea, i ll try.

Or better yet to close quotes window?

do it both :wink:
