server response is slow
I have a many server in in remote site , they are in same network , same segment , the hardware should be the same , but sofware / program in the server is a bit different .
I just found that one of them have problem , the response is relately slow , when I use ssh to connect it , the login prompt take about 10 second to pop up , while other machine have very quick response.
checked that the firewall is enabled , which all server are also enabled firewall , so I don't think it is the reason
ip6tables 0 off 1 off 2 on 3 on 4on 5 on 6 off
iptables 0 off 1 off 2 on 3 on 4 on 5on 6 off
I also checked the server resource utilization is very slow , and the server run normal after login .
it is redhat EL 5.3.
Can please advise what is wrong in my server ?
