+OpenStreetMap tiles
+-------------------
+
+
+Scenario notes
+..............
+
+As a benchmark much closer to the "real world" use-cases for ``kawipiko`` I've done the following:
+
+* downloaded from OpenStreetMap servers all tiles for my home town (from zoom level 0 to zoom level 19), which resulted in:
+
+  * around ~250K PNG files totaling ~330 MiB;
+  * with an average of 1.3 KiB and a median of 103B;  (i.e. lots of extreemly small files;)
+  * occupying actualy around 1.1 GiB of storage (on Ext4) due to file-system overheads;
+
+* created a CDB archive, which resulted in:
+
+  * a single file totaling ~376 MiB (both "apparent" and "occupied" storage);  (i.e. no storage space wasted;)
+  * which contains only ~100K PNG files, due to elimination of duplicate PNG files;  (i.e. at higher zoom levels, the tiles start to repeat;)
+
+* listed all the available tiles, and benchmarked both ``kawipiko`` and NGinx, with 16K concurrent connections;
+* the methodology is the same one described above, with the following changes:
+
+  * the host used in benchmarks has a desktop-grade Intel Core i7 4770 (i.e. 4th generation, about 6 years old) with 4 physical cores and 32 GiB of RAM;
+  * the files (both CDB and tiles folder) were put in ``tmpfs``;
+  * both ``kawipiko``, NGinx and ``wrk`` were configured to use 8 threads / processes, and were pinned on two separate physical cores each;
+  * (the host had almost nothing running on it except the minimal required services;)
+
+
+Results notes
+.............
+
+Based on my benchmark the following are my findings:
+
+* ``kawipiko`` outperformed NGinx by ~25% in requests / second;
+* ``kawipiko`` outperformed NGinx by ~29% in average response latency;
+* ``kawipiko`` outperformed NGinx by ~40% in 90-percentile response latency;
+* ``kawipiko`` used ~6% less CPU while serving requests for 2 minutes;
+* ``kawipiko`` used ~25% less CPU per request;
+* NGinx used the least amount of RAM, meanwhile ``kawipiko`` (due to either in RAM loading or ``mmap`` usage) used around 1GiB of RAM;
