Anyways, will fix this locally and share test results.

Thanks, I look forward to the results.


Set up for this time was slightly different. So, taken all the numbers again.

Boot to shell time (in ms): Experiment 2
[1] Base : 14.843805 14.784842 14.842338
[2] 64 sized fixed cache : 14.189292 14.200003 14.266711
[3] Dynamic freeable cache : 14.112412 14.064772 14.036052

So, [3] (this patch) looks to be improving 750ms (on avg from base build).
