Re: Handling Polling and CPU Bottleneck for Large Image Capture in areaDetector

["Kim, Kuktae via Tech-talk" <tech-talk at aps.anl.gov>]

Hi Mark,

We performed some optimizations on the IOC by following these steps:

1. Increased the CPU priorities for the areaDetector plugins from 50 to 70.
2. Assigned CPU thread 4 for scans, and CPU threads 8 to 28 for plugins.
3. Set polling features to Passive when capturing images.
4. Disabled all unnecessary plugins, enabling only the required ones.
5. Enabled multithreading for applicable plugins.

After these optimizations, we can capture images at 26 Hz, the maximum frame rate supported by the camera, using the full sensor size in HG/LG_HS_12bit mode.

Best regards,

Kuktae

Hi Mark,

I’ve attached a few OPI screens for your reference.

Best regards,
