No, but it may prevent you from getting an accurate measurement for a short sequence of writes.Originally Posted by mynickmynick

Compilers can produce warnings - make the compiler programmers happy: Use them!

You can get around this by making your test use direct IO. Open the file with the O_DIRECT option set, and it wont cache the writes. Keep in mind that you will need to make all your writes page aligned (usually 4096 bytes).
