This is used to index the proxy's name and it contains a copy of the pointer to the proxy's name in <id>. Changing that for a ceb_node placed just before <id> saves 32 bytes to the struct proxy, which is now 3112 bytes large. Here we need to continue to support duplicates since they're still allowed between type-incompatible proxies. Interestingly, the use of cebis_next_dup() instead of cebis_next() in proxy_find_by_name() allows us to get rid of an strcmp() that was performed for each use_backend rule. A test with a large config (100k backends) shows that we can get 3% extra performance on a config involving a static use_backend rule (3.09M to 3.18M rps), and even 4.5% on a dynamic rule selecting a random backend (2.47M to 2.59M).
