A e-shop has developed using perstashop and put to the three server:
the first 2 are amazon EC2, should be same setting
the last one is just local hosting
The problem is server 1 loading very slow compare to the other two server, but the performance should be the best among 3. The speed should be 1>2>3, however, it turn out to be 2>1>3
From http://tools.pingdom.com/ , I suspect that the server 1 need around 10s before it actually start download the file, while server 2 start at 3s, which make a huge difference
Also, when running a http://www.monitis.com/traceroute/ it looks like it doesn't make it all the way to the destination, seems like some sort of network issue.
What takes the long load time for server 1? Just consider it as an PHP site, any ways to check why it is slow?
Thanks a lot for helping
