Looks like it shaved a couple hours off. Nice. I'm curious why your elapsed time is in seconds and not hours/minutes/seconds. I'm still working on new testing logic. I pulled that straight from the log file in the config dir.

It looks like I got a little but of a speed bump. 2/2/2016 13:05 45340 88.2 MB/s 0 3/1/2016 12:44 43864 91.2 MB/s 0 4/5/2016 12:47 44275 90.4 MB/s 0 6/7/2016 13:28 46698 85.7 MB/s 0 7/5/2016 13:33 46998 85.1 MB/s 0 2016 Sep 6 14:30:40 39639 100.9 MB/s 0

Same here. Same here too. DOH! LOL!

I don't really know enough about the inner workings to help you with that question. These are my settings right now. The Recommended Sync Speed is md_sync_window=576 at 149.3 MB/s Tunable (md_num_stripes): 1152 Tunable (md_sync_window): 576 Tunable (md_sync_thresh): 288 Tunable (nr_requests): 8 This will consume 65 MB with md_num_stripes=1152, 2x md_sync_window. This is 6MB more than your current utilization of 59MB. I'm going to reboot back to ESXi, and I have a scheduled parity check next week. I will just see what the results are. Hopefully its better than it has been. Thanks, Pauven!

Well, I don't know what to make out of these results either. Yes, this is a short test, but the numbers seem rather low. This time, I booted bare metal, instead of in ESXi.

I forgot to run it last night before bed. I will download the latest version and run it tonight.

Cool, thanks. I see enough volatility in those results to say you should definitely run the Normal test. Interesting, I see that the CPU and RAM values are missing. This comes from lshw. When you get a chance, can you give me the output of: lshw -quiet -businfo -c processor -c memory Thanks, Paul Maybe because I'm running in a VM?

unRAID version? Your signature says 6.0. 6.2-RC4 And your signature still says 6.0 That's a graphic. Im not going to update it every version.

unRAID version? Your signature says 6.0. 6.2-RC4

I will give it a go.

Thanks, Zeron!

This is the "For Sale" section of the forum. I believe the OP is trying to sell two cards and a cable. The link to Amazon was so you can see the specs on the card.

Based on the way Plex is calculating the required free space, i'd argue you don't have enough RAM SSD's can handle the rigors of writing the transcode, most are rated at 100's of TB's before they start "dying". http://www.extremetech.com/computing/201064-which-ssds-are-the-most-reliable-massive-study-sheds-some-light I would take that argument!

I have done just that since the Emby Docker came out. I used Emby inside my house and Plex outside.

A new version on VMtools is needed every time the kernel is updated in unRAID. So, yes.

Why a new Docker instead of just updating the exiting one?

Plex 0.9.14.2 is broken. Roll back to an older version.

Zeron, you're single-handedly the only reason I'm still able to run unRAID under ESXi. So thank you so much. Ditto!
