I should also note that these tests just run bonnie++ without any special arguments. I will most likely re-run these with -b to enable fsync() calls after writes, which will do a better job of simulating real-world loads.

I'd be interested to see reiserfs (-o notail) included purely because I have an old squid box now straining under I/O load. Back in the day, reiserfs was the received wisdom for squid. No idea what my new squid box should run, maybe your graphs will give me a hint.

@Bernie, Yep I will definitely be bringing Reiserfs into the mix during my next round of testing.
However, I'm going to wait a few days for 2.6.23-rc3+ to hit rawhide, since it apparently contains some optimizations to the I/O layer.

I should also note that this was done on some OLD hardware. It's not meant to show how fast my machine is, but how the different filesystems compare to eachother.

Good quality leather feels very comfortable, leather, metal and very bright, very satisfied! Quality is very good, a little big point, but that's okay, work very well, and is very satisfied with the quality of delivery is very good, is the leather. Whether or carrying a messenger are super nice, it is recommended to buy good quality, leather, workmanship is very good, prices are not expensive, a good choice, praise good quality, real leather, carrying the right size, the packet capacity is also very, very satisfied.
