Hi,

ok, so lets see i ran it too:

 curl -sL https://yabs.sh | bash -s -- -i -g -n

And then i modified the yabs.sh script to test 128k size ( default zfs size ):

Could you please do that too?

So download the yabs.sh file, and on line 616 you will find:

```
Block_SIZES=( "4k" "64k" "512k" "1m")

And this you modify to

Block_SIZES=( "4k" "64k" "128k" "512k" "1m")
```

Or you can also replace the 64k with 128k or what ever. Luckily they build the script clever in this part as array so we can easily modify it.

Please test again and let me know the values for 128k.

I am wondering why you end up with this numbers:

```
Block Size | 512k          (IOPS) | 1m            (IOPS)
  ------   | ---            ----  | ----           ----
Read       | 56.95 MB/s     (111) | 72.19 MB/s      (70)
Write      | 59.93 MB/s     (117) | 77.00 MB/s      (75)
Total      | 116.89 MB/s    (228) | 149.19 MB/s    (145)
```

Normally it should be higher. I dont like this numbers. They are too small!
