Export speeds are limited from recording servers?Hi we are exporting 1 week of severeal cameras , each week. I have noticed that the export speed from Xprotect Client is only 0.5Gbps . We have 10 GBit line and would like to utilize that speed.

I tried the ExportSample from The MIP component examples.

and i see that while Xprotect client only exports 1 camera at the time.

the ExportSample export one camera for each recording server at the time.

We have currently 3 recording servers here.

So for my case i get 3x speed using the exportSample, but still one camera only gets copied at 0.5Gbps.

Is there a way through Xprotect client or ExportSample to remove or change the limit?

First, please verify to use the newest SDK.

Sometimes it’s due to local resource bottlenecks: network speed (from Recorders to client) and disk performance on the Recorders as well as on the client workstation.

In case of using privacy masks with exporting to .MKV or .AVI containers (or via MIP SDK), the footage will be re-encoded to MJPEG video, which is very CPU-intensive and as a result, it takes very long time and extreme amounts of disk space for the exports created.

In some cases, we have managed to speedup the performance using the RecorderConfig tool and increasing the Read Buffer values (requires some experimentation and restarting the Recorder multiple times). Regarding this, please check this KB: https://supportcommunity.milestonesys.com/KBRedir?art=000033266&lang=en_US

Thanks

We are running 20.3a

I have looked at the article, will export speed and archive speed use the same setttings? as the article describes higher speed on archive?

"Archiving Threads

When archiving to or from a network storage area, the rate of data transfer may not make use of all the available bandwidth.

Increase “Low Priority Archive Threads” from 1 to 2. (Higher values can be used but with diminishing returns.)"

We are exporting only Xprotect format and i believe this will primary be a copy effort.

I am also testing it from a client that is connected with 10Gbit speed,

Using a client with 1gbit speed doesnt make a difference. as it seems “capped” at 0.5-0.6gbit.

Regarding the export speed it is important to understand that the export, to work reliably and not break the recording, opens the media database and reads it the same way playback of the video does. Tweaking the speed is not an SDK question as the MIP SDK can only use the same methods as does the Smart Client. As this is rather a general issue please ask again in the support community, you should get better help from the partners using the support community.
