ActiveX component vs CPU usage

Hi all,


I am begining of the ActiveX component.I would like to know that can ActiveX component reduce the CPU usage while running the vb App. In my situation, I have an app that with will get data from third party device via com port(i am using do...loop to get varianty data). Now, i would like to move the part of "get data from third party device" to activeX component.Example as below:

'******app********
do
1)get data from third party device [this part will move to activeX control]
2)validation and display
loop
'****************

My concern is , will this action reduce the cpu usage?

P/s: Now my application's cpu usage is almost reach 100%,i would like to reduce it

thanks in advance
