thanks for your reply thomas. for me, there is two cases of slowness. - the rpc is quite slow. i am using it to return a few thousand by eleven column of data(String).... - i have a tabset within my application which i copied from the smartgwt showcase.... when i click on new tab with google map on it...... it will normally hang and need a few minutes to finally display the result. sometimes, it will hang forever.
can you give me some links to these tutorials? if you have any..... thanks again..
