Zeus Tuning: ------------------ For details on the Zeus tuning parameters used please see: http://support.zeus.co.uk/faq/zws/v4/entries/tuning.html The following tunables are the Zeus global parameters (global.cfg): tuning!bind_any Boolean: have server sockets bind to IPADDR_ANY default = yes tuning!cache_files 8192 Size of the web server file cache (number of files) default = 8011 tuning!cache_flush_interval 31536000 Time after which unaccessed files are flushed from the cache (seconds) default = 120 tuning!cache_large_file 1048576 Minimum size of a "large" file (bytes) default = 1048577 tuning!cache_max_bytes 0 Maximum size to reserve for cached files (bytes) (0=nolimit) default = 33554432 tuning!cache_small_file 4096 Maximum size of a "small"file (bytes) (system page size) default = 4096 tuning!cache_stat_expire 31536000 Time for which the response of a stat() call is cached (seconds) default = 17 tuning!num_children 16 Number of child zeus.web processes to run independent of the number of CPUs (the default, however, is set to 1 per CPU initially) default = <#cpus tuning!so_wbuff_size 1048576 Size of the socket write buffer (bytes) default = tuning!softservers no Enable 'software' virtual servers default = yes tuning!unique_bind no Force each child process to bind to a unique IP address, and not to each interface default = no tuning!use_poll yes Boolean: use poll() instead of select() default = yes tuning!cache_cooling_time 0 Zeus imposed delay before caching recently modified files starts (seconds) default = 120 tuning!cbuff_size 65536 Integer: cgi buffer size default = 8192 tuning!ssl_sessioncache_size 5011 Integer: Size of ssl session cache. Should be prime (default 199) tuning!ssl_sessioncache_expiry 120 Integer: Number of seconds cache data are valid for (default 24 hrs) tuning!ssl_keepalive yes Boolean: Whether to keepalive SSL connections (default yes) tuning!ssl_diskcache yes Boolean: use 2nd level on-disk cache for storing SSL session information (default no if num_children = 1; yes if num_children > 1) tuning!keepalive yes Boolean: enable 'keepalive' (default yes) tuning!sendfile yes Enable sendfile on platforms that support it. (default yes) tuning!sendfile_minsize 1 Size in bytes of the smallest file to be sent with sendfile. (default 32768) tuning!sendfile_maxsize 2147483647 Size in bytes of the biggest file to be sent with sendfile. (default 2147483647) tuning!listen_queue_size 8192 Size of the TCP listen queue. This is the second argument that gets passed to the listen() system call. (default 256) tuning!so_rbuff_size 0 If set, we will set the socket option so_rbuff_size on the server socket. This will also affect the size of the socket buffers in all accept()ed sockets. The value is the size of the socket buffer in bytes. (default notset ) tuning!modules!cgi!cleansize 0
