@LivingSoul - Please do that

You really shouldn't be < 100MB/sec so there must be something quirky going on.

@frederico

I find your results very interesting. All are equal or slower than most of the lowendproviders commented here.

miTgiB · December 2011

@yomero The test is not the same though

dd bs=1M count=256 if=/dev/zero of=test oflag=dsync;sync

If LEB providers received $30 for what we charge $4-6 we could get away with 10 clients on a node as well.

Certainly, thanks for noticing it :P

It is okay man. I am not complaining at all. It has been up and stable since day one and that is what it is most important to me.
