Takes too long to zoom in 100%

LR5.2
CPU: i5-3380M @ 2.9GHz
8GB Ram
Win7

Prebuild 1:1 Preview

Takes 5-10 second to zoom in 100% on 5d3 or 6d Raw files, that have not been edited. I think that's too long. How to bring it down under a second without hardware changes? I can not imagine modern computers require 10 seconds to display an image?

On my Quad core iMac with 32GB of RAM, it takes less than 2 sec to load a 1:1 after having deleted the 1:1 preview and reset the image to the default with LR6.6/LRCC2015.6. Your post says that you are running LR5.2. You can update to LR5.7 without having to cough up any more money. This might help. Upgrading to Win10 while it is still free and upgrading to LR6.6 will go a long way to improving performance.

What is probably limiting your performance is the dual core processor and only 8GB of RAM. Another thing to check is your virus scanner, If you have not excluded the files the LR needs to create the 1:1 preview, the virus scanner is interfering with LR's i/o requests and having to "approve" all files before turning them over to the LR app

What module are we talking about here? Library or Develop?

If Library, and you have definitely got an up-to-date 1:1 Preview then you are absolutely right....it shouldn't take 10 seconds to display the image. But just to be clear, is the 5-10 seconds just the time to zoom in AFTER the image has been loaded into the Loupe, or does it include the initial loading period (though either way 10 seconds is too long, and the zooming part should be pretty well instant).

If Develop, then there'll be a "loading" period of a number of seconds while the original raw file is converted, but once that's done (and 10 seconds is too long for 5D3 files) zooming in and out should again be instant.

What's your setup? Where is the catalog (and previews), and where are the image files stored? How big is the catalog (i.e. number of images)? How long has this been going on, is it a new issue or has it always been this slow? What about other apps, do you have any slowness concerns with those?

Until we understand a bit more about where the problem is happening, it's not really possible to make suggestions. From my own personal experience I wouldn't advocate upgrading to Windows 10 in the expectation that it'll boost LR performance, if anything it had the opposite effect on my Windows system. There may be other reasons to upgrade, but fixing LR performance issues wouldn't be on my list.

Just be aware that the deadline for the free upgrade to Windows 10 is July 28. After that, you have to purchase Windows 10 retail.

Jim,

Real simple. Upgrade now (by July 28) = free. Upgrade later = over $100 for exactly the same OS.

If Microsoft releases OS upgrades that perform worse than the previous version, then they are expecting us to be bigger fools that we are.
I suggested the upgrade to Win10 as an overall performance boost not just for LR. As well as for the ticking clock on free upgrades to Win10. I also suggested updating to LR5.7 (because it is free to the OP) but not with ay real expectation that if will provide sub second display rates. The OP expressed a desire to improve performance without any hardware changes. Based upon the OPs current hardware configuration, this is probably not realistic. So, software changes are going to be the only hope for improvement. That includes upgrading the OS as well as LR.

From my perspective, if the OP is correct that it takes 5-10 seconds to zoom to 1:1 when 1:1 previews already exist, then there is something not right on the system. Yes, the current hardware isn't the fastest, but it's only marginally slower than my Windows desktop, so it shouldn't make that much difference (it takes around 1 second to zoom to 1:1 with previews pre-built on my system, using 5D3 files). Advocating the free upgrade to LR5.7 is fair enough, but advocating an upgrade to LR6 and Windows 10 is not something that I'd personally do as the starting point, I'd want to do some investigation of the current problem first (hence the questions that I asked in my first post). Such an upgrade, by itself, isn't likely to see the 1:1 zoom time get down from 5-10 seconds to where it should be. That might only happen if the current software/hardware install is so messed up that the upgrade sorts the mess out....though on that basis a repair/reinstall of Win7 would also likely fix things.

In terms of Win7 vs Win10 performance, I have been running a series of timing tests, using the same set of images, on every new release of Lightroom since LR3. Over that period I have additionally added my OSX system to the test cases, and have upgraded my Windows 7 system to Windows 10 (though in the latter case the hardware remained the same). As a consequence, I have some historical timing comparisons between the two versions of Windows, and almost without exception there is very little difference....some tests are marginally faster using WIn10, some are marginally slower. The key word being "marginally". Of course, these tests don't cover all LR functions, only some of those that I can objectively measure (building 1:1 previews, and exports). Subjectively, LR performs pretty much the same using Win10 as it did using Win7, the only obvious difference is that startup time under Win10 is a little longer than under WIn7....I suspect there's something different going on with the power management of my internal hard drives, which is probably configurable but I haven't got round to looking into that yet.

thanks the reminder Phil; something I better think about
