That's true. Using bigger buffer will help, but it doesn't tell why reading
large size file is slower than reading small size file.

Both of them.
Reading two 100M files in interleaved way with 16K buffer, 62MB/s

Hello,
I need to read two files simultaneously, and simply read(2) is
interleaved to do this. The problem is the performance varies
dramatically depending on the file size. I'm wondering what is the
problem in this case.
The test application does following:
open 2 files
- the size of two file
Hi BSD guys,
While I was doing simple file read test, I found that there is a huge
difference in file read performance between read() and fread(). I'm
wondering if I'm doing something wrong or if someone has experienced
similar things.
Here is what I did,
For the specific application, I need to
setvbuf(file, buf, _IOFBF, bufsize) solved the problem perfectly.
Thanks a lot.
