Hello alltogether Squid seems to be running smoothly at our school now. We have also made the necassary adjustments to our Aktive Directory, so that every user will use the proxy. SSO is also working. At the moment there are holidays and the request rate is therefore very slim. Next week holdidays end, which is why I thought about making some stress tests before. Do you know any tools which request many sites in a short period of time, measuring the avarage load time, etc?? Or how do you measure the performance of your squid setup? Thanks Benedikt
