Resmods please move it, but only if you can keep the attachments. On a side note if someone could either fix the attachments, or post a simple statement as to what forums have attachments (and at what time of day), or who you have to pay to get the schedule of when attachments show up in one forum or the other...
Anyway, in my continuing attempt to get LL to look at the "pulse lag" issue that has plagued me for so long I have more data. It happened again last night for the entire time I was online (several hours) from the moment I showed up to the moment I logged out.
For those reading for the first time it is characterised by pulsating "spikes" of lag on a regular one or two second cycle, it happens regardless of environment or any objects to be drawn in the environment, textures, tori etc. and under otherwise excellent conditions (good FPS etc.) In fact the "spike" is usually extra noticeable simply because it is displayed against a background of otherwise very good performance.
It is usually an "image update" spike in the fast timers, but often it is a geometry update or even a UI or network update. Sometimes it is a spike composed of all three, but very often the start of the spike contains an "idle" component, as if the system is waiting for information from the server. The only other consistent symptom is the ping (user and sim) are at odds with each other and typically racing up and down the scale from two digit to four digit numbers over a period of less than a second and are also out of sync with each other. On a normal performance day for me, the pings generally go up and down together with roughly or exactly the same values.
Attached are pictures of me at 800 metres in the air away from all objects as before experiencing the pulse lag. More "ragged" spikes this time with more components to them, but essentially the same.
Anyway the further data is that it was suggested that it might be a "sky update" the last time I posted, so I turned off the sky rendering and proved that it wasn't that, but I have an even more interesting piece of data.
I run on a wireless laptop going through a standard wireless router and an ADSL modem, but I have a tennant in the basement suite of my house that also uses a wireless laptop and uses the same router and connection and was actually playing SL at the same time. They had absolutely no lag at all let alone "pulse lag." The two laptops are comparable ("good" machines from last year), but hers is Windows and mine is a Mac.
It seems to me, that this info rules out not only all the "it must be a torus you are looking at" explanations that I typically get, but also any problem with the wiring in my house or my general network setup.
This *has* to be a network problem on the pathway between LL and my ISP or a problem with the coding of SL itself in the way that it handles the network stacks on a Mac vs. Windows under certain conditions.
