Well under 1 second to load geany.html here, and editing it is quite 
smooth as well.

Myself, I've found the biggest slowdown is when having lots of tags 
files, say more than 10 maybe.  If I have all my Vala tags (the ones on 
the Wiki) loaded, Geany basically becomes unusable.  I didn't spend much 
time troubleshooting, but I suspect turning down the symbol update 
frequency might help.

IMO it would be best not to disabling automatic updating of the symbols, 
it's a really good feature.
