I am concerned about my tag structure. Making edits in the datatype takes a long time to save and 50% of the time throws an error. I have tried it on a VM with 16gb RAM and a dev environment on my offices server with the same RAM. Not sure if the environment is not powerful enough or if my structure is too embedded. I have many nested UDTs - ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/0/3/036de380b1b600c126535f488c7fad0d4214ed70.png) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/0/2/0206e05aa5e8d60a6e828447080a6cabb43277c2.png) Each of the datatypes under chemical injection has ~80 UDTs inside (CCISI) this being an “analog” datatype. Each Well under Wells has all these nested datatypes also. Should I rethink this? ---

Can you give more details on the long save times and specific errors being thrown? Also, what is the PLC platform, is this AB Logix and are you using AOIs? ---

The long save times can be a minute or so, or a few minutes, then it errors. It just says error writing to tags, and I can not see the detail section. It will not let me click it, or exit, then it is stuck until I end the Zulu process. ---

What version of Ignition is this? I think there may have been some performance improvements for deeply nested UDTs along the way. ---

I upgraded from 8.1.19 to .20 this morning. Now, I wiped everything of Ignition and I am doing a fresh install of 8.1.20. I was adding to the demo project before. I am doing a clean install now. I will load my stuff back in and see if it performs better. ---

> [@cole.sharrah](#): > > on a VM with 16gb RAM This only helps if you actually configure Ignition to **use** more RAM. Look in your `ignition.conf` file for the settings. (And/or show a screenshot of your gateway's Status=\>Performance page.)
