jQuery Grid Plugin - jqGrid

var st1;

st1=new Date().getTime();//start load grid 

var st2=new Date().getTime() – st1;//load grid end

alert(st2/1000);

i calculate the loading time by top code on the demo,not clude loading data.

first time,the result is about "0.3s" . but in ie6, the time increased after i refresh the grid page,refresh once,increase once.

it is a little worse in version 3.8.2,but it is severe in version 4.3.3,the last version support ie6.after i open the grid ten times,it can loaded after 10s.

can you give some help?

thank you very much.
