DPP 4.7.x abnormally slow on macos (Sierra and High Sierra)


I am trying to use DPP 4.7.x on two macs using sierra and high sierra, with the same results. 

After the first few minutes the application turn so slow that even trying to open a menu, or switch a tab in the tools palette takes literally *minutes* with the cursor spinning the beach ball.

 

I have seen people saying DPP was slow, but this is not even the same league. It takes me in the neighborhood of 20 minutes to open and export a *single* image. Then operation themselves are reasonably fast, but then the application stops reacting for minutes. Sometimes even clicking on the background, then back in DPP is enough to watch it spin for minutes.

 

Both the machines are reasonably specced, there's plenty of RAM, 16GB each with over 10 unused. CPU is shown as idle while the cursor is spinning. Nothing relevant on the console. So it must be some interaction with other software I am using or a bug I am triggering. Just can't figure out where to start looking.

 

It's a shame because I really look how DPP renders colors.

 

TIA,

L.

Hello wmlele, 

In order for the community to better under this issue, we would like to ask a few questions.  

 

-  What is the camera which made these files and how large are they? 

-  Are you attempting to export multiple images in a batch or strictly single photos?

Hello, and thanks for replying.

the photos are taken with an 80D and an M5, and they are standard RAW at full resolution. And I am trying to export a single image, but i have issues with just any operation, not limited to export.

Let me clarify something, first: it is not the export itself being slow. Once I manage to start an export, the operation in itself is reasonably fast. The issue is entirely with the user interaction: doing anything, like clicking a button, touching a slider, pulling down a menu, even bringing a window to front, makes the user interface become unresponsive for tens of seconds.

Say I click on the menu bar to open the 'file' menu: the interface freezes, showing the 'busy' spinning cursor for up to 30 seconds, *then* it shows the expanded menu. And this goes for most 'innocent' operations making a single image process a painful slow process.

 

Ironically, I installed DPP on an old macbook air, which is much less specced than my usual macs, and, while not super fast, is much, much more usable than my macs, on the very same photos, from the same disk drive.

Are your image files on the local machine or on a server? My files are usually on a server, and I get the spinning wheel, accompanied with a lot of activity on my Ethernet switch. I'm thinking that DPP is very inefficient in how it deals with image files that have to be accessed via the Ethernet. I'm using a 100-Mb switch; I'm planning to install a gigabit switch and hope that that helps.

 

I use DPP4 for editing and Irfanview to add IPTC metadata to the generated JPEG file. (Canon, why can't DPP do that? For that matter, why can't it let you add IPTC metadata to a RAW file?) Irfanview does not exhibit the problem.

I normally open my files from a network drive (Gigabit network), but this doesn't seem to be the primary factor: I have tried with local files, and from an external usb-3 drive, and I have the same slowness.

At the same time, on the mac air i mentioned, I access my photos through wifi, and while being visibly slower than local files, and showing the spinning cursor occasionally, it's by no means as slow as on my primary machine.

 

The most relevant difference that comes to mind is that the "fast" Air has a different set of apps, while the "slow" machines are almost identical in terms of the software I have installed.
