My first guess is that there's a network problem. Try this:
run "netstat -rn" and "netstat -r" and note the time difference (if any)
If there's a considerable time difference (-rn is immediate, while -r takes a while)
then it's like that faulty DNS config is the problem.
Just about all the programs you describe as being slow are dependent on network
services. If you start "top", is that slow as well? (top does not access the
network in any way that I know of)
If the test doesn't indicate network problems, you may want to monitor top, systat
and/or other programs to see if you can pinpoint the cause of the speed problem.
