+######## Memory Mapped Access to Files ##########################################
+
+# Whenever you specify 0 for I/O buffer size, memory mapping is used instead.

+# Map this many bytes at once (needs to be a multiple of CPU page size)
+WindowSize             1M

+# When in need to extend a file, grow it by so many bytes (>= page size)
+ExtendSize             1M

+}

+######## Direct Streamed I/O on Files ###########################################
+
+FBDirect {
+
+# Debug: Cheat by turning off O_DIRECT
+#Cheat                 1
+
+}

+######## Temporary files ########################################################

+######## Sorter #################################################################
+

+# 1+2^this files and require a stream buffer for each of them; however, while we are
+# doing that, the sort buffer is not allocated). Set both to zero to disable radix-sorting.
+MinRadixBits           2
+MaxRadixBits           4

+# The same for multi-way merging. The memory requirements are also the same,

+MaxMultiwayBits                4
+
+# If we did not use radix-sorter to the full width, we still might add some more
+# bits to the width to get chunks which are even smaller than SortBuffer, because
+# it can speed up internal sorting later. However, we also want to avoid small
+# files, so we add only a little.

+ThreadThreshold                1M
+
+# Chunks smaller than ThreadThreshold are sorted by a sequential algorithm, but
+# if they are at least of the following size, different chunks are sorted in
+# parallel. There is a slight space penalty for setting up the parallel process,
