Did you do the test on a machine with limited memory? I may have asked
this before, but I don't see a reply, sorry if this is a repeated
question. I find the great benefit when memory for buffers is limited.
I don't know what you call "limited memory".
I used a Dual Opteron with 1 GB of RAM so this may be called a machine with
limited memory.
I test applications on a Celeron with 256MB to be sure they will run on
modest user machines. While CPU is not an issue, I would expect that 1GB
is enough to provide all the buffer space the application can use. I
never see buffer effects on my production machines, when an entire CD
will fit in memory there's not much buffer bontention. A 3GB DVD image
on 256MB shows good benefit from writing with O_DIRECT.
Thanks for testing.
