I use BD free on one of my systems and I don't notice any substantial impact

You are, certainly, a one of your kind.

In the past i had between 600 - 750 , now its running at about 350 MB and it feels light

Plenty of people find it to be light, even though it's heavy for many others.

That's what I call "light"

 

[Pat MacKnife]

You can call this light or lighter , but here Bitdefender is faster and snappier than MD on my pc
Less RAM doesn't mean lighter !

 

[TheMalwareMaster]

I personally don't find any substantial impact to system startup time and system performance in general with BD Free with respect to when I was using Windows Defender + COMODO Firewall

"Zero" percent cpu usage!

Indeed, but MD is even slightly lighter.

If you had more ram, it would use more. This is on a 16 GB ram system.

On systems with more than 16 GB, like 24/32, the usage usually is over 200 MB.

I have 8; B uses 400-500 on the same 8 while idle.

Since you guys are talking about light AV, on my machine the Dome just uses 25MB of RAM.

Light but retains the minimum level of efficiency; If I seek the ultimate lightness, I would remove MD and go on AV-less.

I hear you. What I observed is Panda mostly lags behind in the Detection especially for very fresh samples. But they do get added from time to time thou.

It can be sufficient for a person with the right online habits.

Does depend on system & resources I rarely notice much difference between AV's either, but the lighter the better IMO - I have to say I use neither of these AV's though.
