Hello, i have a big problem and hope that you can help me. i have a media service (streaming, downloading contents with proxy service) with round about 30k requests per day (rising trend). sometimes the load is so high that a visit to the page takes about 30 seconds or more. somtimes you'll get just a 504 Gateway timedout . This problem is sinced i switched php5-fpm from 127.0.0.1:9000 to "fastcgi_pass unix:/var/run/php5-fpm.sock" i don't know where it comes from or what the source. The RAM ist nearly empty. The Down-/+Uploadrate is ~20%. If the load is too high, you can no longer visit the site. Sometimes I see at the logfiles that some customers connect several thousand requests per download link. Others need for the same download 5-10 requests. (Depending on the client or downloadprogram.) In this case, requests will be processed only slowly and with difficulty. what can i do to boost my configs? i am using nginx+php-fpm & debian 7. I am grateful for every tip, for any help and support. here are my configs: My Hardware: My Hardware: CPU: Intel(R) Xeon(R) CPU E3-1230 v3 @ 3.30GHz Cores: 4 physical + 4 virtual cores (hyperthreading) RAM: MemTotal: 32849608 kB Bandwidth: 300mbps IP's: 2 HDD: SSD Raid1 nginx.conf: http://pastebin.com/6usBQbrX vhost.conf: http://pastebin.com/TTqyMbnX fastcgi_params: http://pastebin.com/pDAxN3KG mime.types: http://pastebin.com/0fsMWEZ5 /etc/php5/fpm/pool.d/www.conf: http://pastebin.com/sgDuybqj Code: listen = /var/run/php5-fpm.sock pm = ondemand pm.max_children = 500 pm.start_servers = 25 pm.min_spare_servers = 25 pm.max_spare_servers = 75 pm.max_requests = 0 /etc/php5/fpm/php5-fpm.conf: http://pastebin.com/Pg3cX0zA php.ini: http://pastebin.com/z3hRYEmz thanks a lot
