Lag in the morning

It is about 5:00am PST. There are just under 2,000 residents logged on.

Before logging on to SL, I check my own bandwith levels between home (L.A.) and S.F. : 994 / 369 kpbs. This is supposedly a 1.5/750 connection, but hey, whoever expects much of ISPs. 994 is fast enough.

After logging on to SL, and after a few minutes, my ping rates to LindenLabs measured by my local pinger are under 40ms. That's a round-trip. Not bad.

The debug screen shows ping times exceeding ONE SECOND, EACH WAY. A TWO SECOND ROUND TRIP. I can hardly move.

How can it take under 40ms for a message to travel from my computer to LindenLabs and back, but over 2 seconds for a message to travel from LindenLabs to my computer and back?

With great difficulty (two seconds per character is slower than I can type) I submit a debug report and logout.

I had the same issue after the updates i could hardly move and tp'ing was impossible even after relogging in sl & rebooting pc even with all graphics settings turned to low.

Hopefully it will sort itself out soon as this is getting more and more irritating.

Pings are processed by the lower level IP stack (they have to be), pings are also small and very simple to turn around. "Ping Sim" is a measure of how long an SL level packet (not a ICMP_ECHO_REQUEST "ping" takes to propogate up the IP stack to the sim server, processed and passed back all of which takes considerably more time and is handled partly by user code and not only the kernel.

Despite the similar names they are quite different protocol exchanges and so might expected to be propotional (unless the sim is troubled) but 100ms "Ping Sim" is quite typical and is likely not the cause of your specific problem.

Sorry this tells you only what it isn't. I have no guesses as to what it is.

ADDED: sorry pre-coffee mis-read - 1000ms Ping Sim times are terrible and as far as I'm able to divine represent the sim is troubled. There are some pretty heavy memory leaks in the sim servers which cuase their performance to degrade after they've been up a while. Ask a Liason nicely to reboot the sim if possible; this often clears them.

Did you download the optional update to 1.8.4(7)? If not, do so -- that will probably fix your problem. Lagging due to certain textures is a known problem with the version that was first released yesterday (1.8.4(6)?).

Thanks for the explanations.

I am running the most recent update, and I was having the same problem before the update.

And the problem does not appear to be specific to any one sim. I experience the same trouble whereever I go.

I just want to be clear -- the latest version that fixes the major lagging problem is the *optional* update that came out later in the day yesterday. The update released earlier in the day, which may still be the default, required update, is what causes the problem. And it seems to cause it anywhere there are at least some moving textures (on torii?)

Anything beyond that, it's someone else's turn, as I'm still a noob on a Mac and we're going far afield from my expertise..... Sorry I can't be of more help.

nm. I just read that the 1.8.4.7 viewer has recently been made the official required version....

Yes I have installed the latest, yesterday called "optional," version.

Suddenly -- all problems have disappeared. No two-second pings. No single digit FPS. Response hasn't been this good since 1.6.

The SL ping times are only accurate when you have a good frame rate. As the client gets bogged down and client FPS drops, the ping times go up. This is not a reflection of network performance, but an indication that the SL client is so busy that it is neglecting the network.
