Willy Tarreau 0d6c75d749 OPTIM: freq-ctr: don't take the date lock for most updates ... It's amazing that the value was still incremented under the date lock, let's first use an atomic increment for the counter and move it out of the date lock to reduce contention. These are just counters, we don't need to take locks if we're not rotating, atomic ops are enough. This patch does this, and leaves the lock for when the period is over. It's important to note that some values might be added just before or just after a rotation but this is not a problem since we don't care if a value is counted in the previous or next period when it's exactly on the edge. Great care was taken to ensure that the current counter is always atomically updated. Other minor cleanups were performed, such as avoiding to reload the value from memory after a CAS, or using &~1 instead of two shifts to remove the lowest bit.		2019-05-25 20:31:53 +02:00
