I have extremely high data block wait time....

block   73821695
wait      4835256

The script I ran for this is:

select   CLASS,
         COUNT,
         TIME
from     sys.v_$waitstat
order by CLASS;

We are experiencing very bad performance.

Help?

Are these problems new or been around for a long time? Any increase in users or large amount of data being added or removed?

Sounds like you have out of date stats or are doing a large number of full table scans. Would get some commonly run queries and see what the explain plan is.
