[pve-devel] bug in diskio throttling option to drive?

[Alexandre DERUMIER]

how to do get the 85MB/S ? 
for inside the vm ? or from proxmox graph ? 


do you use cache=none or writethrough ? 


what is the backend storage ? (scsi,rbd,lvm,...) ?

Hi, 

i've made some tests with disk throttling while the iops limit and write 
limit seems to work fine the read bandwith limit does not seem to work. 

I've set the read limit to 120MB/s but i'm just getting around 85MB/s. 
With another disk not limited in read i get 1082MB/s so the backend 
can't be the problem. 

Any ideas? 

Stefan
