[syslog-ng]php-syslog-ng

Dear friends, I have a problem with php-syslog-ng. When my database for a device is big and i try to view the report, it shows the message: Connection time out of 30 secs. Do you know how i fix this? Is there a way to "tunning" the php-syslog-ng? I read something about caching, but i didn't understand very well. Best regards, Tales Teixeira.
