+/* The number 470 has come up by considering the 2MB benchmark

+ * Relay FS buffer pool has been considered as 2MB and based
+ * on that the number of sub buffers are 1100, 2200 and 255.
+ * For Cypress and pine, since the buffer size has increased
+ * to 16K, if we would have considered to keep the relay FS
+ * buffer pool size as 2MB then the number of sub buffers /
+ * CFR records would have been lesser in number (around 130)
+ * So, the decision had been taken to keep the sub buffer
+ * count to 255 and as result the relay fs buffer pool size
+ * in case of Cypress and Pine exceeded 4MB.
+ *
+ * In case of Maple, since the Buffer size is small (4470B)
+ * we have decided to maintain the relay fs buffer pool size
+ * as 2MB, as a result the number of sub buffers has become
+ * 470.
+ *
+ * RelayFS memory required:
+ * Max sub buffer size * Number of sub buffers
+ *
+ * Cascade: (2200B  * 1100) ~= 2MB
