ok...a friend of SL told me for the lags, and she also told me it's normal when they (Linden Labs) do an update, the grid can lag for maybe a week before getting more stable and less laggy.
is that true?
Yes and no.
It used to be the case that when they restarted the grid, all the sims would shuffle onto different servers, which would mean that the local (to each sim) asset cache had to be refreshed from the asset server, which caused many many many hours of slower than usual performace grid-wide.
In recent updates (the last 2 or so) they are working on (may have completed?) a system by which the sims are tied to the servers across the restart, which should massively mitigate against this performance issue.
However, when the grid comes back online, there are
so many login attempts compared to normal that it is just devastating for the user and asset servers, so there is ALWAYS a slowdown.
I would say that the first 24 hours after an update are probably not the best time to do empirical analysis of performance of the new versions.
The very best way to know how a new version will react to your system is to log into the preview grid(s) regularly, and if you see perceived problems,
bug report them. That way, brokenness will never (well, less often) make it onto the main grid in the first place.
It doesn't take much - just 10 minutes of flying around, clicking stuff, trying things out - there are even a set of tests provided in Morris that you can try.
