I've noticed that since I upgraded my PC, that DIYnot is slower. Maybe just coincidence, but on my old, slow, single-core, DIYnot was always the fastest site to load/use.
Now it's always the slowest. I ofen get 'waiting for response from DIYnot' at the bottom left of my screen, and generally slow response. Other times it's fine.
Since changing PC, everything else has speeded up quite a bit. Maybe my PC doesn't like DIYnot??
