Lightroom: LR4 extremely slow web module gallery building

We just released a second RC version of Lightroom 4.1, available at http://labs.adobe.com/technologies/li... .

This issue is fixed in the new RC build.

The team will probably want to know what OS/Version you're running.

I am running Windows 7 64 bit with all the latest patches and upates to the OS. I am also using TTG CE2 pages 5.2.1

I should also add that I am running it on a 64 bit I7 machine with 6Gbyte of DDR3 RAM. I have fast WDC 10,000 rpm drives and a modern motherboard. The slow part of the process seems to be when the image files are being exported, each one seems to take an age as can be seen from the progress bar, the processor usage is not high during this exporting of files only about 20% and neither is the memory usage high. The hardware and storage configurations are exactly the same as when running LR 3.6 but the process is much slower and unreasonably so considering the hardware that I have invested in to get the performance.

Just exported 89 images into a gallery with 89 thumbnails and various other folders etc as part of a Turning Gate Client Response gallery. The export time was 14 minutes, and I was also using LR4 in develop mode

OSX Lion 10.7.3, MacbookPro 8Gb 2.2 Ghz i7.

Hamish do you happen to be able to compare that timing with the previous version of LR? I allowed my catalog to be updated and so can't easily do a like for like test.

I've just exported the 89 images into a separate directory, and opened L3.5.
time to start making the web gallery ( eeish my mac does not like working with 3 versions of LR at the same time)
The export will be done with LR4 not running on my computer - of course
time start 11:07 finish time.......11:11.

EEish, that is RUBBISH LR4. I've been using the beta for weeks to upload galleries and forgotten that it was not good.
Tony, there is your proof
same exact gallery 4 mins on LR3.5 and 14 mins on LR4.
That is 3.5 times S L O W E R

Similar results to those of Hamish, above. Using Vista 32 bit, but no TTG or other extras, this is just a standard LR Flash Gallery. Have gone back to 3,5 until 4.2 comes out...

I'm seeing the same slowness here. Web galleries export quickly UNTIL LR gets to the images, then things really s l o w down.
I'm also using TTG CE2 components

Windows 7 64-bit
AMD Phenom II X6 1090T
16 Gbytes RAM

Here are my timings on a Mac, using the EXACT same HTML Gallery preset in LR3 and LR4:

LR3 114 images to HTML 1000pixel web gallery: 4min 35 sec
LR4 114 images to HTML 1000pixel web gallery: 13 min 27 sec

Mac Pro 12 core 2.66 Ghz
20 GB RAM
ATI Radeon HD 5870
OS 10.6.8

Time to get this fixed Adobe! For me, it's not worth paying for an upgrade to software that takes NEARLY 4 times as long to do a job that I do EVERY DAY.

To all contributors to this thread. I note that at the top of the thread where I had started it the flag indicates that one person has this problem. It seems that contributors have the option to increment this count but I don't think anyone has. I reckon that this might be important in the process of getting attention and some resources allocated to the resolution. Shall we all click on this soon so that it represents the number of complainents more accurately?

I'm creating a web gallery in Lightroom 4, and cannot believe how slow it's running... it's taking literally at least four times as long to run in LR 4 as the same gallery created in LR3.6. Everything else seems slower to. I'm running MacOS 10.7.3 on a MacPro 8-core 2.8 with 8GB RAM.

Lightroom 4 runs impossibly slow..

I, too, am experiencing the same slowness issue on export.

iMac i5 with 16Gb RAM and 10.7.3, TTG Client Response Gallery.

Same, 2011 Macbook Pro, 10.7.3, i7-8gb RAM; TTG Impact WSPP

I did run comparison tests between LR3.6 and LR4.0 on exporting a WebGallery:

• Win7 64-Bit


• Intel i7-980x


• 24GB Memory


• Fast disks


• HTML gallery with 451 images


• Vast majority is CR2's from Canon 5D MkII and 1Ds MkII (approx. 15-25MB each)


• Detail image settings: 70% quality, 1024 px

Results:

• LR3.6: 20 minuts (approx. 22.5 images/minute or 2.7" per image)


• LR4.0: 87.5 minutes (approx. 5.2 images/minute or 11.5" per image)
