This is used for per-prefix stats reporting. The default is ":" (colon). If this option is specified, stats collection is turned on automatically; if not, then it may be turned on by sending the "stats detail on" command to the server. -t, --threads= number of threads to use (default: 4) -R, --max-reqs-per-event maximum number of requests per event, limits the requests processed per connection to prevent starvation (default: 20) -C, --disable-cas disable use of CAS -b, --listen-backlog= set the backlog queue limit (default: 1024) -B, --protocol= protocol - one of ascii, binary, or auto (default: auto-negotiate) -I, --max-item-size= adjusts max item size (default: 1m, min: 1k, max: 1024m) -F, --disable-flush-all disable flush_all command -X, --disable-dumping disable stats cachedump and lru_crawler metadump -W --disable-watch disable watch commands (live logging) -Y, --auth-file= (EXPERIMENTAL) enable ASCII protocol authentication. format: user:pass\nuser2:pass2\n -e, --memory-file= (EXPERIMENTAL) mmap a file for item memory. use only in ram disks or persistent memory mounts! enables restartable cache (stop with SIGUSR1) -Z, --enable-ssl enable TLS/SSL -o, --extended comma separated list of extended options most options have a 'no_' prefix to disable - maxconns_fast: immediately close new connections after limit (default: enabled) - hashpower: an integer multiplier for how large the hash table should be. normally grows at runtime. (default starts at: 0) set based on "STAT hash_power_level" - tail_repair_time: time in seconds for how long to wait before forcefully killing LRU tail item. disabled by default; very dangerous option. - hash_algorithm: the hash table algorithm default is murmur3 hash. options: jenkins, murmur3 - no_lru_crawler: disable LRU Crawler background thread. - lru_crawler_sleep: microseconds to sleep between items default is 100. - lru_crawler_tocrawl: max items to crawl per slab per run default is 0 (unlimited) - no_lru_maintainer: disable new LRU system + background thread. - hot_lru_pct: pct of slab memory to reserve for hot lru.

(default: 64) - track_sizes: enable dynamic reports for 'stats sizes' command. - no_hashexpand: disables hash table expansion (dangerous) - modern: enables options which will be default in future. currently: nothing - no_modern: uses defaults of previous major version (1.4.x) - ssl_chain_cert: certificate chain file in PEM format - ssl_key: private key, if not part of the -ssl_chain_cert - ssl_keyformat: private key format (PEM, DER or ENGINE) (default: PEM) - ssl_verify_mode: peer certificate verification mode, default is 0(None). valid values are 0(None), 1(Request), 2(Require) or 3(Once) - ssl_ciphers: specify cipher list to be used - ssl_ca_cert: PEM format file of acceptable client CA's - ssl_wbuf_size: size in kilobytes of per-connection SSL output buffer (default: 16)
