Creep Love & Performance Upgrades?

I have been impressed with the direction LOTRO has taken since the new Executive Producer, Severlin, has taken the reins:

A new raid
Performance improvements for many
Open communication via Cordovan with the community
Seeking feedback from the community on the direction it would like to see LOTRO go
U18 and 19 were both very well done from a content perspective
Epic storylines have been fantastic
Premium housing

And today they dropped that Bullroarer will be open to test out performance upgrades and creep love:

Fellowship/Raid performance improvements:

Target effect updates have been streamlined. We hope that groups will notice a performance improvement, especially a reduction in client hitches when first targeting a mob or player with many effects on them.
The clean up of effect information when a target is defeated has been streamlined. We hope that players will notice better performance in cases where many mobs are defeated, or when a boss with many effects is defeated.
Our particle effect system has been updated to hopefully make better use of information caching. We hope that players will notice better effect display performance over time during a play session.
