If you have all OutputControl:Files set to No then EnergyPlus will not output a MTR file nor ESO file. The ESO file must be output for ReadVarsESO to function.
If performance is a concern, I would suggest using the native C++ CSV output instead of ReadVarsESO. To do this, you need to select Yes for Output CSV in theOutputControl:Files. If you use the native CSV output, you can keep all the files in OutputControl:Files turned off. One thing to note is to make sure you do not use the -r flag on the command line interface otherwise it will still try to use ReadVarsESO even if you've request native CSV output within the IDF.
