Blocklist mem-cache just got even better!

Just a few days ago we shared exciting news about the TTL-aware memory cache we implemented in front of our Blocklist, which was able to reduce by up to 90% the need to query the DB to check whether or not a client IP is already blocklisted.

Well, we worked hard over the weekend, and we tuned the mem-cache algorithm to achieve even better performance. Let the numbers speak for themselves:

{
  "rejectedConns" : 883,
  "addedToBl" : 4,
  "hitsOnBl" : 857,
  "hitsOnBlCache" : 855
}

That’s a 99.76% effectiveness rate. On to the next task now…
