PC: Gabrien + 5 hires, wild surges, Stormsinger procs, full bard songs/buffs on all, just to see if that mattered; I'm PST zone.
Quest: Catastrophe, R1
Not much "lag" while moving through the quest. Slight stutterings during some spell castings that hit full mob groups at once, hires appeared to have no problems moving/attacking/teleporting. Big boxes/barrels rooms: after first sonic blast in each room, it took ~10 second delay with multiple castings of sonic blast (after cooldowns) before the subsequent blasts would affect boxes/barrels (e.g., casting animation worked, spell points spent, boxes/barrels did not explode). Overall MUCH smoother than what I typically see on Orien, though there were still some slight hiccups.
1st box room - latency 22.0 - 28.0 ms, 0.0% packet loss, sent: ~350-450 Bps, received: ~150-500 Bps; frame rate: from ~35.0 down to ~20.0 on first sonic blast, ~35.0-30.0 on second and third sonic blast

2nd barrel room -
latency and frame rates same as above; Got stuck for a moment in the doorway after my first sonic blast for about 10 seconds, completely locked in place and unable to move during that time.

Moving around in Marketplace, no notable lag/issues. Same for Harbor.
In the bank, took ~15-20 seconds to load up shared (0 items), character (46 items), and TR cache (179 items), latency 21.0 - 25.0 ms, 0.0% packet loss, sent: ~350-450 Bps, received: ~150-500 Bps; frame rate: from ~63.0 down to ~43.0; (Standard): You are on server 66 at r1 lx272 ly32 i2049 cInside ox-52.58 oy219.75 oz-156.29 h136.4.

Quest: Trials of the Archons, R1 solo (no hires): Always have bad lag/rubberbanding while platforming in this quest on Orien (entrance, tar area, etc.). No lag while platforming at all. Small amounts of stuttering as demons teleported into hallways, frame rate never dropped below ~21.0; no lag during puzzle tiles at all, everything operated smoothly; no lag during end fight.

Quest: Spies in the House, Elite solo (no hires): no lag, stuttering, or rubber banding during quests, including with air jets; made jumping a little harder since I was expecting to get hung up mid-jump as usual, but had no lag problems at all

I did not have time to group, or raid, so I can only give solo player feedback. I have no idea if any of this was helpful at all, except I'll say that this was a much better experience overall in every way (platforming, puzzling, load screens did not get stuck, etc.), especially vs. Orien. Also, I did not have time to log in and out of multiple characters, over and over, which usually results in me having to reboot the game after 10-15 character swaps, with each change usually getting progressively worse in terms of responsiveness (hopefully someone else tested that). Anyway, thanks, SSG folks, and good luck!
