Demo: Scrolling laggier with clusterize than without it #13

I'm using firefox on windows; scrolling 5000 rows without clusterize is perfectly smooth; with clusterize it's noticably laggy (at a rough estimate say 10fps). Scrolling performance does remain consistent even with lots of rows.

I observe the same effect with Firefox on Linux.

Scrolling 5000 may be smooth if you have powerfull PC, although in this case the plugin should run smoothly too, strange. I was forced to use 5000 rows in tutorial because of mobile users. Try to set much more rows in playground to see the difference (Append -> Append... -> Destroy table inserts all rows to the table) http://nexts.github.io/Clusterize.js/#playground

Chromium on Arch behaves as the demo expects. Scrolling without is painful, with clusterize is silky smooth.

Thank you influenza, hope others are experiencing the same effect, anyway there's nothing I can do to speed up DOM manipulations.

Demo is painfully slow (list viewport becomes blank) in Firefox and noticeably slow in Chrome with the clusterize-content class, removing it makes it work as expected. I'm not sure if it's actually needed there for anything, you may want to look into it @NeXTs
