Hi all, In a Zope + Zeo 2.7.6 installation, with no request hitting the Zope instance, I have set up a script that does the same request every second. The response time is 15 to 17ms... So far, perfect. -- BUT -- Every 30 seconds, the response time (for one request) raises to 330ms (an then goes back to 15-17ms) Question : in Zope, is there something running in the background every 30 seconds ? Could it be something related to the Zeo connections / cache ? Thanks for your answers.
