BigBox 7.0 introduces noticed delays when scrolling through games of large platform xml

[Pacman56]

I just installed and tested the official release of LaunchBox / BigBox 7.0 and noticed delays when scrolling through games in BigBox which didn't exist in 6.10.

When moving from game to game using the arrow keys, a delay of 1-2 second frequently takes place which ruins the experience.

This problem is quite noticeable when choosing a platform that contains a large amount of metadata such as my Arcade.xml which consist of 6199 games but is of a considerable size: 28.1MB because of the amount of notes in the notes field.

If I do a bulk edit of the Notes field using LB to clear all value, the delay completely disappeared. However, clearing the notes field is not a solution.
