Super high load averages - all the time

Hello - While trying to setup CrashPlan on the drive I noticed super slulggish performance when in the CLI…

from the very first step. It literally takes up to a half an hour to run. Load averages are always relatively at the numbers below

load average: 14.44, 15.85, 15.42

Top processes always seem to be the following:

Seems to serve up movies just fine without any issues, but working in the cli is painful. 

Any ideas?

Hi, what firmware version you have?

Hi - I’m running v03.04.01-219

Today the loads are somewhat down, but I’m sure that as soon as I start moving and playing files, it will ramp up to the numbers in my post above. From what I’ve been reading, this is not normal.

Ichigo any advice?

Here are loads right now…

I’m not sure where you’re reading that it’s abnormal, because given what you’re showing, it’s completely normal.

In your TOP report, the most active processes are:

wdphotodbmerger   –   The Photos database used by WD Photos is being scanned, recompiled, updated

wdmcserver - Part of the My Cloud remote access updates – possibly generating thumbnails, etc.

smbd – Samba daemon;  you’re reading / writing to a share.

As you can see, the report says it’s 80% “waiting,” as all of those processes are very I/O intensive, and they’re spending a lot of time just waiting for access to the disk.

Hi Tony - I guess I was hoping my earlier posts got some attention. What causes twonkyserver to be so busy? I agree that the current loads are normal.

Any time ANY file is added or changed on ANY share on which Twonky is enabled, twonkyserver will start re-indexing its database.

There you have it :slight_smile: and I’ve been moving files and things fairly frequent since purchasing the hard drive.

Thanks Tony.
