Hi. I'm a novice at PHP, so I frequently need to refer to your online
manual at www.php.net
Unfortunately on my non-mainstream browser -- Netsurf, running on
RiscOS -- the pages at PHP.net are sooooo paiiiiinfully slooooow to
render. If the page is lengthy, it takes ages to scroll.
Curious, I asked the Netsurf developers what mechanism might be
causing the unusual sluggishness.
They investigated and replied:
It's because of this SVG being used as a tiled background on
the HTML element: http://php.net/images/bg-texture-00.svg
Since it's an SVG it bypasses all the optimisations we have
[in Netsurf] for tiled bitmap redraw.
It also isn't a filled rectangle, it's just strokes, so it
doesn't get "knocked out" by our normal rendering
optimisations.
Finally it uses opacity, which wouldn't help either,
although I think we ignore that anyway for now.
It could potentially be optimised by pre-rendering it once
to a bitmap, but it would be a fair amount of effort for
what is a pretty uncommon case.
For now, I'd try just toggling background images off in the
menu for that window, and forcing a redraw.
That final suggestion works here, sort-of, but has to be applied again
and again.
I tried viewing the PHP.net pages from Firefox and Chrome on Windows
and Android devices. Must admit that your background, if it displays
at all, is hard to notice! Is my eyesight missing something?
Dare I suggest to the PHP.net webmasters that you simply dispense with
the SVG background? Is it really worth while?
Thanks for listening. Best wishes from this niche. (And I am
enjoying my forays into PHP.)
