Do you have some kind of automated system that dumps IPs in there? 

It might be worth passing that task off to something that will block those via firewall, like fail2ban or csf/lfd (for Linux). I guess there's something similar for windows (wail2ban? It hasn't been updated in forever but there are forks on github and people claim it still works)

I use csf/lfd on my linux box, much like fail2ban it can watch log files and look for specific lines/words/etc.  It also catches portscans and will block an IP if there are too many connections in a certain time period.  

One of these days I should sit down and clean up my scripts for it, then create a wiki page about it.
