Import speed 1s per image normal on notebook?

[lbo]

Hi all,

IMatch running on a i5-6200 notebook without SSD:

Is 1s per image (24..30MB CR2) a normal value?

This machine will be replaced in the near future, but for the moment I want to know whether this is what I have to live with.

Non SSD, notebook => Medium performance.

1. per image to extract the file system data, extract EXIF, IPTC, XMP, EXIF metadata, map into XMP, extract visual query data, produce thumbnail and cache etc. is quite good.

If the ratio between disk speed and CPU is high you may squeeze out a few % by making some tests with the number of threads used for importing metadata & importing file data See this article in the knowledge base for more info: https://www.photools.com/3225/configuring-process-control-slow-media-cd-rom-dvd-nas/

thanks for the information. I will try to limit threads (but don't expect a vast improvement).

During import I found occasionally 18 instances of exiftool in the task list, so maybe I hit the access time / IOPS limit of the 5400 rpm notebook disk.

I will have a faster CPU and a SSD in the near future, and then I will do the initial import and editing on the SSD and then move the finished set to the rotating disk.

IMatch spaws ExifTool processes dynamically, based on the number of processor cores and overall performance. It tries to maximize throughput. A 5400 RPM notebook hard disk (which are designed for low power consumption and shock resistance instead of performance) will be maxed out and hence the bottleneck. 1s per image means 600 files in 10 minutes. This is about the output of a studio day and hence I think it's OK to process that in 10 minutes.

yes, during normal operation even this slow PC is no problem, the time is negligible compared to the other work.
