Currently, OST_MAXREQSIZE is limited to 16 KiB.  This limits the upper size of short i/o (LU-1757) to this size.  This ticket is to examine the implications of growing this limit, to, for example, 64 KiB - The concern is if we end up allocating the larger buffer size all the time for certain operations.

Basically, we/I need to examine the code to see if this is the case, and if it's not, we should look at increasing the upper limit, at least to see if it has a positive impact.
