How many is too many?
Okay. Normally the single block write wait events
(control file/ data file) are the writes which updates
the header and parallel writes usually writes the
actual blocks. So theroitically if you have contention
in single writes (wait event) you can conclude this
many is too many :)
Hope this does not confuse you !!

Have a nice day !!
