That's pretty standard for a cut-thru ToR switch of this style. Cut-thru
switches generally need a lot less packet buffer space than store-n-forward
switches. Also, ToR boxes tend not to have complex qos requirements.

Having said that, you need to be careful deploying small-buffer boxes.  If
you're not careful, you will end up with bad packet loss.
