Visitors from the high speed/high abuse networks that were previously required to login on their first thread view, will be able to view one thread link before being prompted to login and/or register.
It also means the board will be much slower at times as we have track all those ip addresses now. Load has already jumped from 32% to 55% and we are just getting a good start at this.
If so, consider storing the IPs as a hash, or even simpler, make 256 files based on the initial octet of the IP address. That reduces the amount of data in each file while still having a reasonable number of files, and the filenames and data organization "make sense" at the human-readable/editable level.
Maybe you're already doing something like this, but that jump in the load sounds excessive.
Ya, that's alot of files, but beats loading something in and parsing it every page view. The overhead is in the file system. I'd rather abuse the file system than max out memory.
That should be good to 50-80k ips an hour (which is our historical peak load).
So far - it isn't nearly as bad as I had thought.
220.127.116.11 - 18.104.22.168
so you can just check the range if it falls into it or not.
Think this would save some IO and be faster to boot, and not require any more memory then your other solution.
* First thread view from any IP is now open and unfiltered. Current time out is the cron job that does email (about 20 mins).
I am curious why you made this change – is it to sort of offer a glimpse/ “teaser” what is available when they register, or….? Also, I am presuming that supporters area is not included in this change
