RE: async I/O with DB writer and LOG writer

Hi 
KC,

The 
whole idea behind using async I/O is that DBWR and LGWR will not block each 
other out. That is why there is no need for multiple copies of 
each.

  async I/O with DB writer and LOG writer
  
  Dear list,
  
  I recently discussed the effect of 
  using async I/O with DB writer and LOG writer with someone, I was told that 
  async I/O is more beneficial to DB writer than LOG writer, what is your 
  opinion?? Can the difference be quantify?? I thought aysnc I/O with DB 
  writer can be compensated by multiple DB writers, is there any comparison 
  between the two??
