Oh funny.... Eset in the Version 12 didn´t have this problem. But the Windows Filtering Platform was the same. Only Eset has changed. So....what? In earlier version of Eset, there was a similar breaking down of network performance. I´d opened a thread in your forum several years ago. And on Symantec I know, that there is not a breakdown in network in this dimension --> downloadrate from 0 to 100 KB with eset 13 and without on 90 to 100 MB!!! An application, which has access to a database on server (over internal 10 Gb network) needs minutes to start! Without eset it lasts approx. 5 to 10 seconds to open!!!
I´ve tested my internet performance at home (real computer, no virtual machine) now. With eset 13 it at 230-239 Mbps, without eset it is 256-265 Mbps. With Eset 12 there was a subtly differenz.
Thanks for the heads-up! A new thread has been started for version 13: https://www.wilderssecurity.com/threads/eset-windows-home-products-version-13.422360/ Please let us continue in that new thread. Thank you all!
