Storing data is slow

So I have been working around with volume claims and persisting data. I got openebs and longhorn to work but I noticed something that is disturbing me.
When I do inserts into mysql with doing dir bind mounting they take 0.015 secs to execute.
Useing openebs I had 0.200 to 1.2 secs per insert.
And useing longhorn I got 0.047 - 0.200 per insert.
Its getting slower, Now I expected it to get a little slower but oh man this is going to effect how our software will work.

Im I doing something wrong, should I just stay with a dir bind? I dont know what to do honestly.
