Memory

The most significant memory requirement for the stack is the space for buffers. These buffers are split into two memory sections: mbuf_sec and mcluster_sec. Current sizes are:  0x100080 Bytes for mbuf_sec and 0x101000 Bytes for  mcluster_sec.

Both these sections should be placed in external memory. L1 and L2 cache can be enabled for this locations. If they are in external memory, enabling of L2 cache brings significant performance improvement.
