How much CTM slow down the disk performance?

Hi There,

Does anyone know that how much the CTM have the impact on the disk performance?

Actually, I’m look for a tool to take a snap shot on one of my physical dev machine which is built for performance tuning and testing. But, I’m not sure that how the CTM actually work and how would it impact the disk usage. I just worried that with CTM installed the performance test result would be unstable.

Thank you,

Yes, It will slow down the disk performance a bit.


Why is that?
