Hi Menge ! Thanks for the tips ! I realize that running squatter every 3h is too often, once my enviroment is still growning, we had around a tousand users but the predictions are to have 50.000 users in a month or two. We are planning to change it to run once each night and maybe at specific times with less IO traffic. After changing the squatter entry on cyrus.conf do I need to restart Cyrus or just a reload is fine ?
