I'm using Debian 8.9 on my old laptop(https://h10057.www1.hp.com/ecomcat/hpcatalog/specs/provisioner/05/GA009ET.htm). It is running fast(as Debian always used to run). I upgraded to 9.0(and later to 9.1) but it started to run slow so I did a fresh 9.1 install(home is on a different partition) but since the start is running extremely slow(including the installer).
Not sure if, in my case, this security feature is causing everything to be (if I'm not exaggerating) 100% slower but is it possible to disable this security feature ?
