Low Performance of DBWR can slow down everything..

Reason: If a foreground process cant find a free buffer to store its read content , it will signal DBWR to write the dirty buffers to disk. DBWR will write dirty buffers and make their buffers overwritable, so foreground process can proceed.
If DBWR is slow, foreground process will wait, foreground process will not able to read. So, associated client will wait for the DBWR in fact.
