hi all,
First time poster, long time lurker.

I'm currently in the process of converting a bespoke flash mapping
system over to using gmaps. The map itself functions ok, but I'd like
to improve the performance in terms of marker displays (don't we all).
Reading around the group, I think using the GSprite might save some
time as I do have a lot of bespoke icons to display. However, I'm not
sure if I'm getting the full benefit from using the open source
MarkerManager as to get to the speed improvements that I am currently
getting I have to call clearMarkers() each time I rezoom or move the
map.

Would any of you kind souls have a quick look at the code and suggest
where I can make further improvements?

(you need to zoom in two levels to start making any calls to the db
and it will initially return towns and attractions in that viewports
bounds + some custom padding size)

I am currently calling the data from a mysql spatially enabled db and
passing the data back as xml to help limit the amount of data found.

I have set a number of preloads in external js files for the images
and have then used them in GIcon() calls.

I have a getMarkers() function that tests the zoom level and then
makes an ajax call if the zoom level is great enough - depending upon
which attributes I need to show. However, I am wondering if I should
break up the ajax call and chunk the data back to the map rather than
use GDownload() and wait for all the corresponding data to be
returned? - this is the main problem when there are 150+ markers to be
returned back.

I would also appreciate any feedback on optimising the calls made in
my base.js file with regards to allocating the markers types and
categories.

Kind regards,
paul
