Is your video writing to the OS drive?<br>If so the first step I would do is isolate the OS from the data drive so that the performance of the recording does not impact the OS performance. &nbsp;<br>I am assuming this is your issue as you indicated that as disk I/O increases the video stops.&nbsp;<br><br>

Hello,<br>I guess I/O issues you get only solved if you make sure, you have SSDs behind your harddisc...<br>A traditional single harddisc has a I/O rate of around 200 IO /s. A SSD arounf 50.000 or more. <br><br>Robert's hint is right as well. Doesn't matter which kind of harddisc you have, you should always write data onto a separate disc to keep the OS drive only for the OS.&nbsp;&nbsp;
</div>


<div>
The O/S and data are very much on separate RAID 1 drives.<br><br>I was wondering are their Operating System settings that allow you to tweak the performance?<br><br>[Apologies for the delay in replying but was off-lien over the weekend]

<div>
Hello,<br>lets say in comparison to hardware, there is not a lot you can do on the OS side. <br>You can switch off all not needed services. <br><br>But the major components are the graphic card as well a the hard disc. <br>And if you observe I/O issues, than you have to remove the bottleneck --&gt; SSD

Hi - thanks to everyone with their considerable experience in explaining this. I was expecting a series of settings that could turn unnecessary processes off to relieve more processor and GPU capacity. It would appear that that is not the case. Again many thanks.

Got a Microsoft Server 2019 server that just records CCTV data, using an NVidia P1000 Quadros graphics card as the GPU.
I need to optimise the server so it can allocate more resources onto the video and less onto the data as it stops showing the CCTV when the disk I/O is under load.
Where should I start?
