Difference in performance: local machine VS amazon medium instance
- by user644745
I see a drastic difference in performance matrix when i run it with apache benchmark (ab) in my local machine VS production hosted in amazon medium instance. Same concurrent requests (5) and same total number of requests (111) has been run against both.
Amazon has better memory than my local machine. But there are 2 CPUs in my local machine vs 1 CPU in m1.medium. My internet speed is very low at the moment, I am getting Transfer rate as 25.29KBps. How can I improve the performance ?
Do not know how to interpret Connect, Processing, Waiting and total in ab output.
Here is Localhost:
