This is something really odd I yet to fully understand, but for time being I’ve decided using localhost on AWS ec2 is bad. (at least on Windows Server 2008 R2)
I think it might have something to do with internal DNS or address routing, but my nginx-reverse-proxied tomcat is 4-5x slower when I bind it into localhost as opposed of the local IP. We’re talking 1 minute to load a 300kb css file!
Open a command prompt and run ipconfig /all and your local ip should be under IPv4 Address under Ethernet adapter Local Area Connection 2:
On tomcat, edit your server.xml, find your
And finally update nginx.conf to point the reverse proxy backend to above IP.
After doing this now my reverse proxy is much faster, only few seconds to load 300kb css file.
