Willy Tarreau fc630bd373 MINOR: listener: improve incoming traffic distribution ... By picking two randoms following the P2C algorithm, we seldom observe asymmetric loads on bursts of small session counts. This is typically what makes h2load take a bit of time to complete the last 100% because if a thread gets two connections while the other ones only have one, it takes twice the time to complete its work. This patch proposes a modification of the p2c algorithm which seems more suitable to this case : it mixes a rotating index with a random. This way, we're certain that all threads are consulted in turn and at the same time we're not forced to use the ones we're giving a chance. This significantly increases the traffic rate. Now h2load shows faster completion and the average request rates on H2 and the TLS resume rate increases by a bit more than 5% compared to pure p2c. The index was placed into the struct bind_conf because 1) it's faster there and it's the best place to optimally distribute traffic among a group of listeners. It's the only runtime-modified element there and it will be quite cache-hot.		2019-03-07 13:48:04 +01:00
