Hey, Im using tomcat, its running on localhost port 8180, without AJP 
and works quite fine. I dont see any actual issue with it.

Maybe try to eliminate AJP connector, just use it the clasic way and it 
might work better, try also this kernel settings:

net.ipv4.tcp_timestamps=0
net.ipv4.tcp_fin_timeout = 1
net.ipv4.tcp_tw_recycle = 1
