Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Virus-Checked: Checked by ClamAV on apache.org Hello, I've been working on my project for months now, it is my first WebApp project. Yesterday, I deployed the project on my dedicated server and a soon as I reached about 80 users, the webapp became really slow. However, the cpu usage of the server was very low (never more than 15-20%). I have no idea of what is the cause of this slowness (server config, bad programming..). Can someone help me to diagnostic the problem? Where shoul I start looking? thanks in advance, St�phane H. --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: users-unsubscribe@tomcat.apache.org For additional commands, e-mail: users-help@tomcat.apache.org
