Max List Size
If you have a field that has a list and it loads very slowly then the size of the list that it loads needs to be limited.
You first open the Registry or regedit. Then you find this location: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\SimpleIndex\Misc
Then you right click in the space to the right and select New>String Value
Then you name this new entry this: MaxListSize
Then you double click on it and set the size of the list that it loads. We suggest somewhere between 1000 and 5000
