Question: Is read_multiple the best way to readout a set of values frequently for every 100ms?

[MBL-DGS]

I want to readout a set of 20 variables every 100ms even when the value did not changed.

I tried subscribing to a variable which changes every nanosecond and subscribe to it every 100 ms. Then define the variables to read from, and lastly add a read action to obtain the value. (see image below).

I saw the option, read multiple. Is this much more efficient/ computationally effective , since i sometimes get connection failures after some time it is deployed.

This is the example with multiple read:
