While old, the article does a good job explaining the quality aspect but does not really mention it\'s relationship to time required to generate each jpeg. The inference most will assume is that a lesser quality setting takes less time to generate. So I took a few minutes to see for my self using a MacBook Air mid 2012, 2 GHz - i7, 8Gb ram.
56 photo Raw files (30.1Mb avg size), LR 6.7 export setting sRGB, resize 990 pixels long edge, 120 resolution and std sharpening for screen. Times are mm:ss
THEN: tested the same files on my iMac late 2012 3.4 Ghz - i7, 32Gb ram with same settings
#4 2:16 avg jpg size 259k <same as #3
Conclusion: #1-3 tests show essentially the same results thus indicating it\'s the math being done by LR for each file to be converted regardless of output settings in quality or resolution. Test #4 shows that applying brute force (more powerful equipment) to the task makes a big difference, approx 50% improvement.
So, if you have a lot of files to export the faster the machine will do it quicker.
