theHarvester considerably slower than it used to be?

[V1rtualHack3r]

Hi Guys, is it me? I have noticed that the latest release of theHarvester in both Kali 2019.3 and 2020.1 is really, really slow. I started an OSINT scan running about 4 hours ago and it's still running, admittedly it's a -b all switch but even still. Anyone else noticed this?

There could be some more reasons that make it slower. Consider the following
1) How big the domain or target you are attempting to scan
2) How much data they have discouraged(Subdomains particularly),

Are you even using proxy? that could make it a little worser
I have worked on theHarvester online, but it's pretty faster
