We have some new WCF services we are hosting on our shared infrastructure. As part of testing the developers have asked me to enable WCF tracing. This maybe a vague question as I understand there are several available sources for this (System.ServiceModel,System.ServiceModel.MessageLogging,System.IO.Log,...etc) But is there some info anyone can furnish me with if I should enable tracing for these in terms of the performance hit my servers will take.(CPU Utilization, memory usage, pagefile usage, dat write to cache speed, etc) I have other applications on these servers that I need to be concerned about. (Granted this is only a test environment) . If any one has any info or casn point me to some info it would be greatly appreciated.
