COMODO and ESET have always been less of a drag on system resources than Bitdefender and Kaspersky. Actually, COMODO has always been the lightest - excluding a full system scan with heuristics set to maximum.
That's what they report, but the reality of what I see on my specific test systems does not match their published test results.
That's why these tests are mere guidelines - something to consider in the absence of reliable, accurate infos - and just a very basic comparison\selection tool.
All that matters is what a user experiences on their specific system.
I have a bit of concern about the performance test result as kaspersky always slows down my copy speed noticeably while avast almost cannot notice the difference (with transient caching disable -> maybe this is the reason)
That's interesting, I didt see that, but like @hjlbx said, for me what I saw in different PCs is way different. I found Kaspersky and BD slow down my PC significantly compared with ESET or Norton, even running them in a i5, 8GB RAM.

For one thing AV test labs do not consider a long system reboot caused by\as a result of an installed AV a system slow down; only the system boot time from completely off is considered.
So that is why I am saying there is a lot of details left out of these reports that the vast majority of users would consider important in evaluating the softs.
