It may not be the full answer (it depends on the kind of data inside the value), but before doing CoTaskMemFree(pItemValue), you should also do VariantClear(pItemValue->vDataValue). That's a possible leak in the Read part, but it will only show itself with strings or other kinds of VARIANTs that have additional pointer in itself.

But, if you are looking for a leak related to AddItems: You are not freeing the pErrors that you get from AddItems. You are only freeing the pErrors you get from Read.

It is the best way to look into the implementation of Reference Client and Reference Server (e.g. via "UA Quickstart Application" solution) because they are certified. In case of doubt, use them as reference:

This seems to be IO Bound.

Does the PLC support concurrent reading well? Sounds like it's bottlenecking.

Try reading from two different PLCs and you might get faster results as well.

If you just add some dummy calculation (or Thread.Sleep()) in mymethod(), you will see that it runs faster in parallel.
