Slow Performance Troubleshooting

[Jmtyra]

Looking for some feedback and suggestions for troubleshooting the slow performance of Sighthound. Specifically the remote access function via the web interface and the mobile app locally, not over a mobile/cell connection. Current configuration is as follows:

* Windows Server 2012 R2, fully patched (VM)
* 8GB RAM (5gb ~ 6gb used/active)
* 4 vCPU (30% ~ 50% utilization)
* 80GB OS drive, 8TB video storage (iSCSI, max ~10ms latency)
* RAM disk configured for Sighthound AppData folder
* Remote configuration, using 'low' quality for both clip and live video
* Wired 1GB LAN

Viewing live video locally in either the web interface or mobile app locks up, won't play clips and the live video feed is hit and miss. All storage resides on a NAS device.

I'm sure there are more details that I'm forgetting, please let me know and I'll update this post accordingly. Currently running some performance tests on the NAS to eliminate that as the bottleneck but any ideas are welcome at this point.

Thank you!

4/27/2017 Update: As a troubleshooting step, the entire virtualized environment was destroyed and re-created from scratch. Virtualization hosts, network configuration and storage. After this was complete and the Sighthound VM was brought back up, the remote access performance issues remained.

Does the web view / mobile app lock up, or is it the desktop application itself?

We have quite a few remote access changes under development, if you'd be willing to participate in a beta of those please fill out this form and we'd be happy to include you once we have a build ready for sharing.

Hi Ryan!

Only the web view / mobile app exhibit this behavior; the desktop application is very responsive and quick.

I submitted the form for the beta participation.

Thank you!

I experience slowness via web/mobile. Submitted form for beta access.

I see that v5.0 was released yesterday, hurray!!

These entries for remote access make me happy:

• Adaptive quality control for live streams, dynamic resolution and bitrate based on connection speed
• Much faster connections for live streams
• Web access has improved dynamic layout, massive speed improvements, and expanded HTML 5 playback support

Downloading now, can't wait to try it out.

Web interface works great, much improved. The mobile app is faster but the clips never load, anyone else have this problem on Android. If I use the browser and go to the. Website instead it works fine.

I have a similar problem in playing back clips. Sighthound mobile is set to "play clip as streams". If the source is 16:9 it plays fine. If the source is 4:3 then I keep getting "clip load error". It seems to happen to my Android 4.4.2 phone only. Newer phones seem to be ok.

(Note: The feedback below is based entirely off of the mobile app, connected via the local WiFi with all traffic routed internally. The web-based GUI was not tested due to network segmentation.)

Reporting back on this issue, just upgraded to v5.1 and *WOW* the difference in the mobile app responsiveness is night and day. Amazing, truly amazing. The live view is very quick now; from app launch to connection and streaming is only a few seconds. If the app is already running in the background (but not connected to the server) then it's basically a second or less.

Previously recorded clips is very interesting. When looking at the list of clips for "today" the thumbnail display is darn near instant. Not sure how you smart guys and gals accomplished that, but that's quite impressive. Even scrolling down rapidly will still show the video thumbnail with almost zero delay until you get past the 'buffer'. Again, *WOW*. Actually viewing the recorded clip is, of course, a bit slower but manageable. Before it would either not load at all or take quite literally 30 seconds or more to play the clip. Now it's roughly between 10 - 15 seconds before the clip begins to play. This might be due to my local setup, who knows, but it's still a LOT better than what it was before.

Thank you again for all of your hard work developing and improving this product. It makes me feel confident that I made the right choice when purchasing a license.
