Before revision:  However, unlike accessing an object replica, access through a recovery set composed by an XOR'ed object copy requires downloading content from r nodes , which increases the load imbalance in the system additively by r  .
After revision:  However, unlike accessing an object replica, access through a recovery set composed by an XOR'ed object copy requires downloading content from r nodes , which increases the load imbalance in the system additively by r . We express the system's load balance in terms of the maximal spacing or maximum of d consecutive spacings between the ordered statistics of uniform random variables. Using this connection and the limit results on the maximal d-spacings, we derive our main results .
