Re: scanning user space

Wow.

thanks for doing my benchmark for me Pete.  you gotta love this list ;)

could you elaborate a little on the 'simple data structure' bit for me?

thanks again,

Rick

<snip>
C. Using a 32Kb buffer (just a simple data structure in the program). This
needed about 500 reads.

D. Using a 20-byte buffer. This needed over 800,000 reads.

I ran 5 tests of each type and took the average elapsed time and CPU
seconds
used.

The results were a surprise to me.

A.    43.4 seconds elapsed 3.0 seconds CPU time.
B.    20.4 seconds elapsed 2.6 seconds CPU time.
C.    4 seconds elapsed 2 seconds CPU time.
