APEX all page loads very very slow - Default install with 11G R1

Question

HI,
I have installed Oracle 11g R2 on my Windows XP desktop. APEX is installed by default in 11G R2. I have tried to use APEX but it runs very slow. For example, bringing up the Oracle APEX admin login page takes to 5 to 7 minutes. Once logged in, performing admin tasks is painfully slow as well.
EM is fast, the pages come up in a few seconds. I am not sure of the exact setup APEX since it is installed by default.
Here is what I have tried so far
1) localhost:8080/{I can not remember the rest of the url}
2) ip/8080/
3) tried both IE 6 and firefox.
4) turned off the proxy server in IE options. We are on a LAN and use proxy to internet
I ran a search for a dads file on oracle home, but I can not find it. Maybe it is renamed in 11G r2.
Any help would be appreciated.

Answer 1

Hello,
Check the value of SHARED_SERVERS, if it's set low (which it probably will be if you haven't adjusted it yourself), then you'll probably want to increase the value.
Essentially (if this is your issue) there are insufficient pooled connections available to service all the HTTP connections necessary to render your page, so you're paying a performance penalty waiting for either new connections to fire up, or for busy connections to be free'd up ready to service a new request.
Hope this helps,
John.
