Apache Slow

Dear All,

I have configured FAVEO helpdesk software on my Centos-7 machine. Mariadb has been used for database. Every thing working fine but when i have changed the ip address of the machine from 192.168.0.110 to 172.16.2.8. Now websites pages taking time to display and images are not displaying. I have changed the ip due to switching between internet and intranet.
