NAS Drive Slowdown...
« on: November 03, 2014, 06:13:32 AM »
We shoot large events fairly often.
(Awards shows, conferences etc.)
Workflow consists of tethered camera sending raw files into maxed out macbook pro (large ram ssd).
Live Ingest to onboard hard drive (secondary) and back up ingest to attached NAS drive (Primary) by gigabit hardwire through a gigabit router…
Tethered computer operator is captioning on the NAS drive.
We have two other macbook pros accessing the captioned images on the NAS drive for social media and on site sales.
Everything through hard wired gigabit.
The NAS drive is a Western Digital My Cloud.

Everything works fine until the folder has more than a few hundred images in it…..
Then we start getting serious slow downs…..to the point that it is unusable.

We believe its because Photo Mechanic on all the computers is constantly trying to refresh and the network can't handle it.
We need to shoot raw (although we don't touch the RAW files until after the show). We need to have backup.

Anyone have any thoughts on how to speed the network.
Sports guys must do this all the time….
Would a pro NAS solve the problem?

Many thanks as always!

Hi Marc, I'm experiencing a pretty similar situation, with Windows 8.1 PCs hard wired at 1Gb/s to a Synology NAS.

I open a directory per contact sheet, up to about 20 simultaneously, each containig 1000 to 3000 images (RAW + JPG). The overall disk access speed abruptly slowed down in the last month or so, and the load on the CPU in the NAS stays at 90-99% for minutes, either after opening a new contact sheet or opening or saving a file.

I'm afraid that the problem is not due to Photo Mechanic, even if it gives an heavy contribution to it.

Have you someway solved your problem? How?
If not, if I find a solution I'll let you know.

Marc,
I got a WD MyCloud 4TB myself today.

What I found in a comment at the Amaz*n-site:
Enable SSH on the MyCloud, ssh into the MyCloud as root, sens the 4 commands:
Code: [Select]
#Stop the 2 inventory processes
/etc/init.d/wdmcserverd stop
/etc/init.d/wdphotodbmergerd stop

#Do not start them at a reboot
update-rc.d wdphotodbmergerd disable
update-rc.d wdmcserverd disable

No Reboot of the NAS needed.
Hopefully it helps!
