Large IP deny list

[coldplug]

Hello. I want to filter some services from accessing my webs, for example host-tracker.com and similar. For that purporse I created conf file with really lot of "deny IP;" directives in it. Would this very large IP deny list affect nginx performance? Also, is there a limit how much single IPs can be blocked by nginx?

Thanks much,
Ivan
