Hi. 
When i check Remember my answer in Defense +.
The Defense + is very slow for recorded , and proposed the next window with new rule of Defence +.
When remember is not check it’s instantaneous.
???
Is it normal ?
And solved with next version ?
Or can I do something ?
I use only Comodo Firewall ; Version 3.8.65951.477.
Without AV.
But i had this problem with previous versions.
:comodorocks:
Bye.
;D
This is a known issue and has to with D+ writing the complete rule set to the registry which can get fairly large over time.
So far only a fresh install helps, which will get rid of old and unused rules. After that fresh install use “Treat as: Trusted Application” more often which should result in fewer rules.
Also try purging your rules list if you don’t want to do a fresh install.
I’m also very unhappy that Comodo hasn’t fixed that problem yet.
Hi. weaker. (:WAV)
Thanks for help and quick reply. (:KWL)
I had try to do a fresh install with the previous version.
No change for me.
Purging rules work a little better for me.
But that not perfect.
I go to try “Treat as: Trusted Application”.
I'm also very unhappy that Comodo hasn't fixed that problem yet.+1. And me i don't understand why Comodo not working on this problem. It's the only one default of this soft for me. Comodo firewall is the best firewall. (:CLP) Pity.
Did you uninstall the old version first? Usually it’s feeling very snappy in the beginning when the ruleset is empty and getting slower over time.
If you installed over the old version, your settings (and rules) are kept.
Best regards,

Yes 
I :
Uninstall the previous version.
Cleaned registry ( cccleaner etc…)
Reinstall.
Erase multi configuration.
Purged Firewall and Defense+.
But nothing changed. :-\
Bye.
Try CSC (Comodo System Cleaner) instead of CCleaner, as hopefully the Comodo people know best how to remove remnants of their own software ;D
But honestly, I’m out of advice now 8). For me a fresh reinstall always fixed that problem (of course only temporarily).
I have try.
It’s little beter.
Defense+ is a litle more fast.
But not very concluante.
CSC is goog but dificult at use.
Ever since upgrading to 4.0+ ‘remember my answer’ has been unbearable. Jumped from 1-2 seconds to 15+ seconds with the same config (on a Quad Core box with 12GB of RAM and an Intel X-25 SSD).
And no I don’t want to ‘Trust Applications’ or not have a lot of rules. That is the whole point of using Comodo, to have precise control over who does what, and phones home to whom. MS doesn’t need to phone home every time I start RDP, or launch WM Player. ‘Wiping your config’ is also the stock answer that wastes hours of my time and patience recreating rules that I’ve already created but Comodo is too slow to remember.
Absolutely the same inconvenience on a WinXP SP3 system. Upgraded from latest V3 to latest V4 and used CSC to clean after uninstall. Preserved all the rules and imported successfully yet everytime a new app wants something, CIS stalls for close to 10-15 seconds.
I have disabled Logging for both Firewall and Defense+, no difference.
Appreciate any ideas!
