WOW! Those differences are crazy!<br><div class="gmail_quote"><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

Please - I know benchmarking takes a lot of time - but could you check<br>
something: the behavior those fs have at what time they flush data from<br>
cache to disk is very different. Have you made sure that you measured<br>
the time it really needs? I mean the difference between:<br>
<br>
$ sync; time cp source dest<br>
and<br>
$ sync; time (cp source dest; sync)<br>
<br>
Only the last measures somewhat correctly.<br></blockquote></div><br>I had noticed that there was, say, 5 seconds of disk activity after the cp command complete which I assumed was buffers getting flushed, but 5 seconds didnt seem that significant overall. I will run the tests as you suggest and post back. Do you think btrfs (with or without compression) would be faster than reiser? If so I will try that as well.<br>
