`<div dir="ltr"><div>i am using Raidz2 with 4 drives. <br><br></div><div>i am using dell 490 with 2x3.0 Xeon processors. <br></div><div>12 GB RAM. <br><br><br></div><div>1 40gb HD for omni OS<br></div><div>4 different size disks for Raidz2. set of 2x160gb and 2x250 gb.<br>
</div><div>every thing is working well except VM file transfer performance. hosted on NFS.<br><br></div><div>when i SCP from omniOS to another linux server it copy<br></div><div><br>root@omni:/acipool# scp test.tmp root@10.x.x.13:/<br>

<br><br></div><div>which i think is fine due to Raidz and 2 parities.<br></div><div><br></div><div>however on VM hosted on NFS taking too much time.<br><br></div><div>a file of 500 MB copying from NFS to my desktops took 20 minutes.<br>
<br></div><div>but file from my desktop to NFS is normal. for example a file of 500Mb taking less then a minute to copy.<br><br></div><div>but same file when i try to copy from NFS to desktop some time it shows 100 plus minutes and dynamically changing time but eventually it is taking too much time.<br>
<br></div><div>some time copying from NFS is a bit quicker and some time dead slow.<br><br></div><div>one thing i have also noticed that once the copy is dead slow it suddenly starts copying the data very fast and it happens for few seconds and then again dead slow.<br>
</div><div><br></div><div><br></div><div>any idea what is happening what mistake i am doing here ?<br><br></div><div>any advice would be highly appreciated.<br><br></div><div>i will share my further testing later. <br></div>
<div><br>Thanks,<br><br>Yousuf<br></div><div><br><br><br><br><br><br><br></div></div>
