AW: [Qgis-developer] [WebClient] rule-based style SLOW

It seems to me every second/third request gets no answer, the other 
requests are fast. Maybe one of the fcgi processes has a problem.
If you kill all the processes with 'sudo apache2ctl -k restart', do you 
get the same behaviour with the newly started processes?

Regards,
Marco
