CPU USAGE GOES TO 100% with new 2.4
cpf.exe is a true issue with 2.4 due logging, while cmdagent.exe is (usually) due to monitor dll injections and this has been reported since 2.3. Like Kail stated, the logging issue hogging cpu is more apparent with more simultaneous, active connections.
Version 2.4 – cpf.exe and high CPU
