Logging to redo

Question

Oracle 11.0.1.7:
This is a stupid question. If we don't care about recovering the database and are only testing for functionality purposes then is there a way to not log anything in redo log. Reason is that we are seeing very slow write to redo because of resource issue and are limited with the resource issue. So I was wondering if there is a way to eliminate logging to redo logs. Are redo logs required if DBWR process is refreshing from buffer cache anyways? I do understand that we can't expect any recovery of data, but that is fine. Can someone please give more insights?
I also understand altering tablespace to NOLOGGING doesn't reduce redo generation for normal DML operations.
