Since this is the technical issues forum, is it too much to ask that someone from LL actaully *answer* this post and give all the people experiencing this some idea of what it is or at least acknowledge it as a problem?
Symptoms:
This happens across different machines, for different prople and through many releases of SL (since before 1.6 for certain). If it happens to you, it may (or may not), happen to the person right beside you in the same sim.
It begins when FPS is generally good and ping readings are fine (for me this is about 65 or so on both user and sim), no packet loss, no time dilation, but then out of the blue....
"Waves" of lag, usually every two or three seconds, each lasting about a second where the entire world freezes, the music stream stutters, typing stops etc. It sometimes happens when you initiate a key movement to turn, but that could be just when you notice it cause you are expecting to move and you dont. Similarly it's also noticeable when the music is stuttering, but it's likely not related to that.
The only true, repeatable symptom is (for me anyway) the pings are racing up and down the scale (usually with the user ping and the sim ping being at odds with each other). One rises into the thousands while the other stays in two digits or even goes down, then they reverse places sometimes.
The attatched "fast timers" pics were taken 800 metres up far away from any objects, textures, geometry, etc. but the readings are exactly the same no matter where you are and no matter what geomtry is in the area.
In between the pulses, everything is running fast and smooth and all the bars are tiny and right over on the left-hand side, just as you would expect hanging in the air away from everything in an empty sim.
In the top right corner you can also see both the pings sliding up and down the scale over the course of the three pictures being taken (less than 30 seconds elapsed time).
What it appears like, is that due to some network screwup or the inability of SL code to handle the varying network conditions, that the entire game is freezing waiting (in this case) for an image update. At other times the bar indicates I am waiting for a geometry update, but I dont have pictures of that yet.
Obviously there is no image that I am waiting for 800 Metres in the air and obviously even if I was, the entire game shoujldn't freeze waiting for a single jpeg or even several.

). Which of course I installed to try to fix the invisibility issues.
