I am using wordpress installation and using some standard plugins.

I have 400 visitors per hour and daily 1500 unique visitors. Database size is 50MB. but it has 1200 posts and 25,000 comments. I think it is creating number of connections when readers connects and stay long time on site for reading articles. I have not made any manual php files. everything is wordpress.

here is the output by running the following command :

ps auxw| awk '{print $6" "$0}' | grep MEM | grep -v grep && ps auxw| awk '{print $6" "$0}' | sort -n | tail -5

Code:

NAME

       dtc-xen_migrate - migrate a VPS to another Xen server

SYNOPSIS

       LOCAL_VPS_ID DESTINATION_HOSTNAME [ DEST_VPS_ID ]

DESCRIPTION

       dtc-xen_migrate	This  shell  script  is a part of the dtc-xen package that is to be used by the dtc panel to manage a Xen VPS server. Note
       that you need rsync in both the source and the destination dom0.

       This script is used to move the content of a Xen virtual machine (VM) managed with dtc-xen to another Xen server of the same type.  The	VM
       destination will first be prepared, then the local VM will be shut down, then it's content will be transfered over using rsync.

       Note that this is NOT a live migration, and down time of approximatively the time needed for the rsync will occure.

PARAMETERS

       LOCAL_VPS_ID The DTC-Xen id of the VM, from 00 to 99.

       DESTINATION_HOSTNAME Destination Xen server hostname to migrate to.

       DEST_VPS_ID Destination DTC-Xen id of the VM, from 00 to 99.

EXAMPLE

       dtc-xen_migrate 19 alpha.example.com 21

       This will migrate the content of xen19 on the local machine to the destination server alpha.example.com using xen21 as VM name.
