Hi, I am running an application with MP2, it's running with two webservers (with DNS round-robin) and a DB server (mysql). The OS is ubuntu Linux, Apache's server version: Apache/2.2.14. Apache handles the requests directly, there is no proxy in front.
Last day one of the server got unique accessing IP 632331, another got unique IP 635232, so the application handles total IP 1267563 last day (and almost every day). All the requests are dynamic, 60% is writing to DB, 40% is reading from DB. Eash webserver has about 500 long connections opened to mysql with Apache::DBI. Both webservers and DB server have light load. For example, the stat for one of the webservers: # pstree init─┬─apache2───518*[apache2] # uptime 22:32:58 up 69 days, 23:26, 2 users, load average: 0.08, 0.08, 0.08 # free -m total used free shared buffers cached Mem: 16073 7752 8321 0 268 5077 -/+ buffers/cache: 2406 13666 Swap: 3813 0 3813 To post this I may want to say that MP just gets good performance. I once wrote the application with other language, not as good as this. Thanks.
