The listeners buckets are a new way of segmenting the listening sockets (called listeners, each corresponding to a Listen directive) into multipe containers (called buckets, a term which often refers to "dividing into" in computing). Each bucket contains a duplicate of all the configured listeners, and each httpd child is associated to (ie. accepts connections from) a single bucket, while the system distributes incoming connections evenly between the duplicates. The "legacy" behaviour corresponds to a single bucket for all the children, hence a high concurrency on each listening socket on heavy load. By creating multiple buckets (configuring ListenCoresBucketsRatio), one can relax this concurrency and let the system do the dispatching accross the children, which improves performances/scalability. I must admit that it's not easy to translate "listeners buckets" in french, but first I think the right term is really "buckets of listeners", so what would be the so-english-inverted-way :) to say it: "listeners buckets", "listeners' buckets" (with the single quote) or even "buckets' listeners"? In french, I personally would use "collection de sockets d'écoute" [mais qui à mon avis n'indique pas assez la notion de duplication et division] or maybe "duplicata de sockets d'écoute" [un peu de latin n'ayant jamais fait de mal]? But you certainly have a bigger experience than me in translation ;) [J'abandonne l'idée de traduire "socket", je crois n'avoir jamais entendu un autre terme pour le/la désigner en français, même pendant mes études avec des profs qui mettaient un point d'honneur à franciser beaucoup de choses!]. By the way, the confusion about the term probably also means that the english documentation of ListenCoresBucketsRatio is not that clear, do you think something should be improved or made more clear?
