P: LR4 extremely slow web module gallery building

Ouch Beat,

over 4 times is worse than many have noted

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)

Beat

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

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

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

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.

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?

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.

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

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'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
