Subject: Decrease tile rate limit to 30 TPS
X-Git-Url: https://git.openstreetmap.org./chef.git/commitdiff_plain/2ecb8ca90ac730ada6e083aebd8f3265033f46d5

Decrease tile rate limit to 30 TPS

This is 15 TPS per server, except for pyrene which needs 30.

Now that the rate limiting is working I reviewed IPs exceeding 20
TPS on an hour basis, looking at several days, and they were all
scrapers, or fakes which I would normally block if not for the effort.
I found no non-scraping proxies or NAT.
