TOP reports High iowait

Hi team,

My server running RedHat Enterprise 3.0 is getting slow two days ago. When I
check performance I can see the value of iowait around 80% - 95%, when my
server is on these values it gets slow to serve web sites and other services
like sendmail. Any idea about this issue?
Server: Dell PowerEdge 750, P-IV, 2.8Ghz, 1Gb RAM, % disk: 13 - 16%
RedHat ES 3.0. Sendmail, MySQL, Apache running virtual hosting. ALl of these
are defaults versions on RedHat ES 3.0

I hope you can give an idea about this.

Best Regards,
Yezid Mendoza.
