Esri basemap render speed abnormally slow in Chrome

Hi everyone,

In my project, using the oceans basemap from Esri is very slow to render when zoomed in very close (for Chrome only). Topo is also slow at high zoom levels, but it is bearable in comparison to oceans.

Using Chromes developer tools to look at the Network timing for the tiles reveals some are waiting 400+ ms, but this is also the case for topo so that's not too helpful.

Profiling using the Timeline tool shows that painting takes considerably longer with the oceans basemap.

You can try it yourself quickly in the sandbox by replacing "topo" with "oceans":http://developers.arcgis.com/javascript/sandbox/sandbox.html?sample=map_simple

Question:

Is there anything on my end that I can do to optimize this in Chrome?
