First, I want to stress test my server [xeon(2x)2.53ghz, 4gb ram] [build by Yii], a stable condition with:
1- Create new recorde -- about 200
2- Update database -- about 250
3- Query database -- about 300
If I use range of request over that numbers I get status of request is null.
And I have another test don't use db [it just send a post name to server and server echo something] -- I sent about 1000 threads request just the number of successful request about 800 and the remainder is null.
So, everbody please help me, about the number of request is that suitable or it's very low, and how to overcome null request response

have you tried ab ? the Apache Benchmarking tool ?
$ ab -n 200 -c 5 http://myhost/the/page/that/creates/the/records
$ ab -n 250 -c 5 http://myhost/the/page/that/updates/the/records
$ ab -n 300 -c 5 http://myhost/the/page/that/queries/the/records
