GlassWire only uses a lot of memory when it has to log an unusual number of hosts simultaneously, for example if you use something like Bittorrent for an extended period of time. When using Bittorrent you can switch to Incognito mode with GlassWire under the "GlassWire" menu to solve this problem.
Another reason this could be happening is that your PC is infected with malware. You can also check GlassWire's graph to see what apps are using so much network activity that would cause GlassWire to have to work this hard to function on your machine.
It is not usual for GlassWire to have memory usage problems.
It's unfortunate you feel the need to bump every thread in our forum that has to do with resource usage in an attempt to somehow punish us for a personal problem you're having with your PC. GlassWire's job is to keep track of network activity and log hosts and it does its job well.
We have spent a lot of time optimizing GlassWire where its resource usage is minimal, plus we give the option for people to use Incognito mode to not log hosts and use even less resources.
Below is GlassWire's current resource usage on my machine which is an older Intel NUC. An Intel NUC is not a very powerful machine.
Your messages would not be the first time people have contacted us complaining about resource usage problems only to find their PC is infected with malware or has a broken or badly behaving application running.
