I use this call
[[!Gmarker? &latlng=`[[*latitude]],[[*longitude]]` &parents=`1108,1110,1111,1112,1113,1114,1115,1116,1117,1118,1119,1120,1121` &zoom=`6` ®ion=`fr` &width=`600` &height=`550` &showHidden=`1`]]

But it takes 15 secondes at least to diplay.

I know i have something like 300 markers, but i wanted to know if there is a way to speed up, should i use a cache system ?
How can i do that ? Is there a a way to avoid these 15 secs ?
