when i do a count(*) an a 1.2GB table, just after an app finishes inserting 20 million records
i can see from iostat that, that disk is being read as well as written to !!!

the only reason i can think of WRITES being performed while being READ is the block cleanout is being performed by the count(*) !!

i would appreciate if anyone could explain further !

regards

PS: 7.3.2 on AIX, the file is raw and async_io is true
