I often shoot hundreds, sometimes thousands of RAW files that I need to then convert to jpeg files. I realize LR is a BETA...but its a UB application that is free and something many photographers use right now. This test will provide two kinds of data...speed of the systems tested AND speed of LR as it is updated. To make it as consistent as possible I've uploaded a test file. Feel free to share the file so the load isn't all on my webserver (I'll try and update links here). right click and save file (change extention by deleting .txt possibly): TEST FILE Here is what you do. If you don't have Lightroom, get it here. Test steps. 1: Make 9 copies of this file so you have 10 total. 2: Move these to: Users>Pictures>Lightroom>Photos>Speed Test 3: Import these photos to your library (file>import). Have LR 'reference in existing location'. Uncheck rename and segment by. Name the shoot "speed test" (or whatever floats your boat). 4: Now wait for LR to stop making the thumbnail previews. Check the activity viewer in LR to make sure nothing else is going on (window>show activity window). If there is, stop it by clicking the red X. ***timed step coming so get your stopwatch ready*** 5: Select all 10 files. If none show up make sure your ratings filter is set to 0 and above. Now go to Export. Use the following settings Trial 1: destination folder user>Pictures>Lightroom>Exported Photos> check 'put in subfolder' and name it 1. Settings: jpeg, 100 (best), AdobeRGB, uncheck constrain size (full res) Click Export and start the timer. LR should make a sound when its done so make sure the volume is up (you can watch progress on the activity window...sounds are in preferences>general). Then repeat with the following settings: jpeg, 100 (best), AdobeRGB, max res 600h and 600w Report the following: -Time in seconds -LR version (Beta 3 for now) -CPU (speed, single/dual core) -RAM -System HD specs, additional HD specs if you store your User or LR folder there. (size, rpm, cache size) -any other system data that would be helpful (quad users...check activity monitor to see if all 4 are used) OK, have at it. LMK if things don't make sense or if I need to ask for more information. It may need more files for the faster machines. If its too fast (under 10 seconds) then feel free to do more and report that in your post.
