1. To test the stability of my Nginx installation, I use a load generator on a static_30K.html page of 30KB.
I added $response_time to my log file and generated 100 threads x 10 loops of static_30K.html
My top show load of 0.01

2. I sorted the timings of the log file in a spreadsheet.
There are 1,000 entries. timing range from 0.000 (600 entries) to max of 0.944 sec

3. The range is on the high side especially the Upper numbers consider my server is no load and it is only one static file

4. Can advise what I can focused to tune on Nginx and even OS

5. I am on the latest developer release on Nginx 1.3.9 running php5-fpm Mysql on Ubuntu Precise.
My CPU is 4 core with 2GB RAM with FAST SSD

6. My Nginx Config are shown below.
