Hi all,

I'm using sun4u Netra(tm) CP2033 Server.
It has 650MHz one cpu and 2G main memory.

And i'm using memory DB and web server there.
Memory DB takes around 1.5G main memory because i have 100000 users on
DB.
So only Free memory is available around 300M on system.

When i request one action from client it goes to web server then php
handles the action and requests again to my Program which handles any
request and returns the result to php after receiving result from DB.
Anyway the Program requests to DB after receiving request from php and
returns the result around 250 users to php and php sends back to the
client.

The point is that if i ask one request it takes around 2 second.
But if i ask 10 request at same time then my program receives 10
request at same time and makes each thread but each thread handles the
request for around 20 seconds.

So if i ask 10 requests the time till i get the results takes around
20 or 30 seconds.
Is it the problem of my program? or just because of the server
performance?
The company member is expecting that the one request takes 2 second so
10 secon have to takes 2 seconds because the server handles
concurently.
Anyone can give me the reason of the slow response?

Thanks.
