Steinar H. Gunderson	23f5d145ec	Previously, processing a large batch of timeouts was O(n^2) in the number of ... outstanding queries, and processing a DNS response packet was O(n) in the number of outstanding queries. To speed things up in Google, we added a few circular, doubly-linked lists of queries that are hash-bucketed based on the attributes we care about, so most important operations are now O(1). It might be that the number of buckets are higher than most people would need, but on a quick calculation it should only be 100kB or so even on a 64-bit system, so I've let it stay as-is.	2007-09-29 18:18:47 +00:00
