*Very* interesting. Thanks for the benchmark stack.
I'm seeing similar results to yours here on linux Mint 17.3, with the 
exception of Append 1280 item texts, where I'm seeing LC9 quite a bit 
faster than LC6.7.11. It's quite consistent across multiple runs. This 
may be due to the fact that LC6 is 32-bit and I'm comparing it with a 
64-bit LC9. For appending 5 item texts, I see a 3x slowdown in LC9, 
similar to your results.

Append 345678 Items texts (of 1280):
LC6.7.11 (32-bit):  4894 ms
LC9.01rc3 (64-bit): 3271 ms
