Dear admins:
Sadly I have to tell you all that I'm experimenting issues of slow showing of this fourm pages. On the other hand, downloading of attachments is very fast (or archives are too small to detect slow speed). The other vast majority of webpages I'm surfing through is loading reasonably fast.
In this particular case I'm using Mozilla Firefox 6.0 on a Windows 7 Pro Edition (with legal license that came bundled with a Lenovo laptop. If it's not FLOSS, at least it's original) As soon as I finish working I switch back to Debian, compare performances and write you again.
I hope this issue is solved soon. I send you all a big hug from the nowadays freezing Pampas (Argentina)
