You really have not given us anything to work with other than "my network slows down over time"

Have you installed the sysstat package and configured sar? Look at the output of "sar -n DEV". Anything interesting? Have you checked if the number of open sockets is increasing over time?

SA2(8)								Linux User's Manual							    SA2(8)

NAME

       sa2 - Write a daily report in the /var/log/sa directory.

SYNOPSIS

       /usr/lib64/sa/sa2

DESCRIPTION

       The  sa2  command  is  a shell procedure variant of the sar command which writes a daily report in the /var/log/sa/sardd file, where the dd
       parameter indicates the current day. The sa2 command handles all of the flags and parameters of the sar command.

       The sa2 command is designed to be started automatically by the cron command.

EXAMPLES

       To run the sa2 command daily, place the following entry in your root or adm crontab file:

       5 19 * * 1-5 /usr/lib64/sa/sa2 -A &

       This will generate a daily report called /var/log/sa/sardd It will also remove reports more than one week old.

FILES

       /var/log/sa/sardd
	      Indicate the daily report file, where the dd parameter is a number representing the day of the month.
