We have a Linux box which is responsible for all things Internet. It's main
job is to act as a news server, receiving a continous live feed from our
We have noticed that when news is coming in the whole TCP/IP sub-system slows
down rediculesly. Using 'top' you can see that the machine has some 9 meg. of
free memory (used as buffers) and has 80% idle time, but any net related
commandssuch as 'route' or 'netstat' will print a bit of their tables and
then freeze for 20 or so seconds and then continue. Remote telnet is the
same. Although the connectforms instantly, it takes a further 20 or so
seconds for the login prompt to appear(same for ftp). Our news feed is via a
64K link and so can't possibly be strainingthe network very much at all.
I have the latest kenel (1.1.45), would the 'load balancing (experimental)'
helpat all? (it's switched off at the moment)
Thanks for any help/comments.
