Thank you for your help.

When it happens, this lasts for a moment, It's difficult to be more precise as when this is the case, I leave the site and return back later. It does not happen on a specific thread: sometime one with very few posts will take forever to be displayed whereas one huge such as "Poser Official > Antonia" will arrive very fast.
My dev point of view suggests an overload somewhere that creates a bottleneck. The random side of these problems makes it difficult to identify the source of the problem.

If I'm alone to see this effect, there may be a random problem between your web server and my destination (Switzerland). In this case, you won't be able to do anything...
This does not happen every day, even though each morning (around 8am in Switzerland = GMT+2 with DST) I check Poser's forums + 5 to 6 in this category, such as this one.

Oh and now, it's responsive...
