The suggestions I have to improve exports and imports:

* Export your data to a file on a drive separate from the datafiles and
redo logs to reduce disk contention
* Export tables concurrently with multiple exports such as the following
two commands:

exp tables=OWNER.TABLE1,OWNER.TABLE2,OWNER.TABLE3 userid=x/y file=file1.dmp &
exp tables=OWNER.TABLE4,OWNER.TABLE5,OWNER.TABLE6 userid=x/y file=file2.dmp &

* Import with COMMIT=Y and play with the BUFFER size to improve performance.
* Check your redo log size. I have changed redo logs alone to improve
imports by 200%!

Hope that this helps,
