Hi Leonardo. You can check the PHP, Nginx and database error log files to find out if there are any problems related to their configurations (maximum number of connections allowed etc.), if you run into a similar problem again.

To increase the load I needed to twiki parameters such as in the $PHP_PATH/etc/php-fpm.conf. pm.max_children pm.start_servers pm.min_spare_servers pm.max_spare_servers pm.max_requests I mis-suspected the network because if I increased the number of clients I didn't see an increasing in the number of nic traffic. But twiking php-fpm.conf I was able to get 100% of CPU utilization. I hope this hint could help others.

Other question, in the tutorial for Web Server it is written: "To saturate the web server you might need to increase the maximum number of connections. As a rough estimate, 700-1000 connections per core should be able to saturate the web server." What do you guys mean by saturate the web server? I ask because my network card is being saturated before the CPU. Is it possible to run the benchmark with more than one NIC? Currently I have the db server in one machine (tomcat+mysql), the frontend in another (nginx+php), and the clients running in other set of machines.

Yes, you can start the workload running the following command on the client machine: $FABAN_HOME/bin/fabancli submit OlioDriver default run.xml You can use the run.xml file under apache-olio-php-src-0.2/workload/php/trunk/deploy/run.xml as the input template. You need to replace the default values in the file with the values of your choice, as you do using the faban web interface. -- Cansu On May 31, 2012, at 1:22 AM, Leonardo Piga wrote: Hi guys, Quick question, is it possible to start the Web Server workload using a script like other application such as Web-search?
