Jimmy_Yang Access to a VF page extreamly slow
Hi all,
I wrote a simple VF page, and overrided the "New" button of Accout with it. Then i clicked the "new" button from the Accounts tab, after selecting a Recordtype and clicked the "Continue" button, it took me incrediblel 20 seconds to call this VF page out, sometimes even slower. But an click on a standard or custom tab won't take me more than 2 seconds to display information of that tab.
I know every first time an end user accesses a vf page, force.com platform application server will retrieves the page from the metadata repository and sends it to the Visualforce renderer for conversion into HTML. And maybe that's why it's so time-consuming.
Any way, it's nonsense to take so much time to show a simple vf page. Is there any thing i can do to solve this problem?
Any suggestion will be highly appreciated.
Paul, thanks for your reply, the code are as below
VF page:
<apex: page Controller="AccountDuplicationCheck" cache="true" expires="600" tabStyle="Account">
<style type="text/css" media="all">
.error {
margin: 0;
padding: 0;
background-color: #00E0AA;
}
</style>
<apex: form >
<apex: pageBlock>
<p>
<apex: pageBlockSection >
<apex: panelGrid columns="4">
