+################################ VIRTUAL MEMORY ###############################
+
+# Virtual Memory allows Redis to work with datasets bigger than the actual
+# amount of RAM needed to hold the whole dataset in memory.
+# In order to do so very used keys are taken in memory while the other keys
+# are swapped into a swap file, similarly to what operating systems do
+# with memory pages.
+#
+# To enable VM just set 'vm-enabled' to yes, and set the following three
+# VM parameters accordingly to your needs.
+
+vm-enabled yes
+# vm-enabled no
+
+# vm-max-memory configures the VM to use at max the specified amount of
+# RAM. Everything that deos not fit will be swapped on disk *if* possible, that
+# is, if there is still enough contiguous space in the swap file.
+vm-max-memory 10000000
+
+# Redis swap files is split into pages. An object can be saved using multiple
+# contiguous pages, but pages can't be shared between different objects.
+# So if your page is too big, small objects swapped out on disk will waste
+# a lot of space. If you page is too small, there is less space in the swap
+# file (assuming you configured the same number of total swap file pages).
+#
+# If you use a lot of small objects, use a page size of 64 or 32 bytes.
+# If you use a lot of big objects, use a bigger page size.
+# If unsure, use the defualt :)
+vm-page-size 256
+
+# Number of total memory pages in the swap file.
+# Given that the page table (a bitmap of free/used pages) is taken in memory,
+# every 8 pages on disk will consume 1 byte of RAM.
+#
+# The total swap size is vm-page-size * vm-pages
+#
+# With the default of 256-bytes memory pages and 104857600 pages Redis will
+# use a 25 GB swap file, that will use rougly 13 MB of RAM for the page table.
