Hello Konstantin,<br class="gmail_msg">
<br class="gmail_msg">
First you have to identify which component is the bottleneck.<br class="gmail_msg">
What's the error in traceback?<br class="gmail_msg">
Are there any clues in /var/log/httpd/*error_log? Tomcat timeout,<br class="gmail_msg">
postgresql timeouts, etc.?<br class="gmail_msg">
<br class="gmail_msg">
