unstable reading tags

[tokke100]

I have setup the node to read a list of tags every second. It sometimes returns every 3 seconds, sometimes 3-4 times in the same second.

Internally, the library performs the following activities in a loop:

• perform a read of the tag group
• perform a write of the tag group
• waits the specified amount of time

So I'd expect that it could take a bit more time than the configured amount, mainly if there are a lot of tags, but not being faster than that. Also, please note that Node.JS (and therefore also Node-RED) is single-threaded, so if your flow is performing other blocking activities, it could affect the readings.
