After answering a defense+ pop-up window, I have to wait more than 20 seconds until the respective program goes on working. During that time cfp.exe requires 50% of processor activity.
With v3 I already had to wait quite a while, but no it’s extreme. It really kills my nerves.
No, I won’t buy a faster machine!

Did you import your old 3.14 configuration file into v4.1? I believe this is due to importing the 3.xx config into 4.1 because the 3.xx config file is not optimized to run with 4.1. 4.1 uses a new config format (.cfgx), and although 3.xx config files are compatible with 4.1, they don’t run as good as compared to creating a new config file for use in 4.1. I notice this extended delay as well since updating to 4.1, and I imported my 3.14 config file into 4.1.
You are right. That’s what I did. But you don’t want to tell me that I should create the whole computer security policy manually again? ???
Well, there have been programs, and quite a few, that offered tools to convert old to new, either with the setup already or later started by user.
I very much hope that COMODO will be compassionate with v3 users who have a wide computer security policy. I hope for a converting tool :a0 8) >:-D >:(
That’s really what you should do to get the best performance, but I’m not going to tell you to do that, because I sure as hell don’t want to do that either. 
Also having a lot of rules will make CIS respond slower when answering to alerts.
It used to be quite slow back before v.3.14 or so, and then the delay kind of disappeared. But, now it’s back full blown in v4.1. I have the same amount rules as in 3.xx, and it is definitely very noticeable again now. Having less rules will help, but I think anyone who imports from 3.14 to 4.1 is going to have some delay one way or another.
