I get similar (high) results:
I guess I must have a really slow usb stick. However, I cannot repeat the 9 minutes odd with ext4 storage - the only thing I can think of for the discrepancy is that I've been working with image files for each of the ext4 and f2fs storage (which also explains the difference in thumbnail files sizes since there were 2 days between me making the images) and it might have got corrupted when I re-imaged the usb stick or there might have been something running in the background (not sure what though).
Anyway re-did the tests (deleting the /downloads/thumbnails folder between each test):
3 tests with ext4 (4GB Sandisk Cruzer):
Code:
openelec:~ # du -csh /storage/.xbmc/userdata/Thumbnails
247.5M /storage/.xbmc/userdata/Thumbnails
247.5M total
openelec:~ # time sh -c "cp -r /storage/.xbmc/userdata/Thumbnails/* /storage/downloads/Thumbnails && sync"

sys 0m 14.17s3 tests with f2fs (4GB Sandisk Cruzer):

sys 0m 10.40sThis still represents approx. 90% increase in performance so I guess I'm going to stick with f2fs.
Quote:What might be interesting is installing a new add-on or skin. I think the write speed would be significant in that.
I seem to remember Aeon Nox took a couple of minutes to install. Installing from a zip file would avoid internet download speed being the bottleneck.
Installing Aeon Nox 4.0.9 from a zip file took 1m 43s for ext4 and 1m 6s for f2fs - I couldn't get texturecache to work (something about JSON-RPC server not running), so I gave up.
