+# Performance analysis
+
+This directory contains tools for analyzing tapper performance.
+
+# Periodic tapper logs
+
+In tapper logs there are some periodic lines that shows its internal state and consumed resources.
+
+Internal state example (formatted and commented):
+```
+stats - {
+	"processedBytes":468940592, // how many bytes we read from pcap
+	"packetsCount":174883, // how many packets we read from pcap
+	"tcpPacketsCount":174883, // how many tcp packets we read from pcap
+	"reassembledTcpPayloadsCount":66893, // how many chunks sent to tcp stream
+	"matchedPairs":24821, // how many request response pairs found
+	"droppedTcpStreams":2 // how many tcp streams remained stale and dropped
+}
+```
+
+Consumed resources example (formatted and commented):
+```
+mem: 24441240, // golang heap size
+goroutines: 29, // how many goroutines
+cpu: 91.208791, // how much cpu the tapper process consume (in percentage per core)
+cores: 16,  // how many cores there are on the machine
+rss: 87052288 // how many bytes held by the tapper process
+```
+
+# Plot tapper logs
+
+In order to plot a tapper log or many logs into a graph, use the `plot_from_tapper_logs.py` util.
+
+It gets a list of tapper logs as a parameter, and output an image with a nice graph.
+
+The log file names should be named in this format `XX_DESCRIPTION.log` when XX is the number between determining the color of the output graph and description is the name of the series. It allows for easy comparison between various modes.
+
+Example run:
+```
+cd $MIZU_HOME/performance_analysis
+virtualenv venv
+source venv/bin/activate
+pip install -r requirements.txt
+python plot_from_tapper_logs.py 00_tapper.log
+```
+
+# Tapper Modes
+
+Every packet seen by the tapper is processed in a pipeline that contains various stages. 
+* Pcap - Read the packet from libpcap
+* Assembler - Assemble the packet into a TcpStream
+* TcpStream - Hold stream information and TcpReaders
+* Dissectors - Read from TcpReader and recognize the packet content and protocol.
+* Emit - Marshal the request response pair into a Json
+* Send - Send the Json to Api Server
+
+Tapper can be run with various debug modes:
+* No Pcap - Start the tapper process, but don't read from any packets from pcap
+* No Assembler - Read packets from pcap, but don't assemble them
+* No TcpStream - Assemble the packets, but don't create TcpStream for them
+* No Dissectors - Create a TcpStream for the packets, but don't dissect their content
+* No Emit - Dissect the TcpStream, but don't emit the matched request response pair 
+* No Send - Emit the request response pair, but don't send them to the Api Server.
+* Regular mode

+In order to run the benchmark you probably want:
+1. An up and running Api Server
+2. An up and running Basenine
+3. An up and running UI (optional)
+4. An up and running test server, like nginx, that can return a known payload at a known endpoint.
+5. Set MIZU_HOME environment variable to points to mizu directory
+6. Install the `hey` tool
+
+## Running the benchmark
+
+In order to run a benchmark use the `run_tapper_benchmark.sh` script.
+
+Example run:
+```
+cd $MIZU_HOME/performance_analysis
+source venv/bin/activate # Assuming you already run plot_from_tapper_logs.py 
+./run_tapper_benchmark.sh
+```
+
+Running it without params use the default values, use the following environment variables for customization:
+```
+export=MIZU_BENCHMARK_OUTPUT_DIR=/path/to/dir # Set the output directory for tapper logs and graph
+export=MIZU_BENCHMARK_CLIENT_PERIOD=1m # How long each test run
+export=MIZU_BENCHMARK_URL=http://server:port/path # The URL to use for the benchmarking process (the test server endpoint)
+export=MIZU_BENCHMARK_RUN_COUNT=3 # How many times each tapper mode should run
+export=MIZU_BENCHMARK_QPS=250 # How many queries per second the each client should send to the test server
+export=MIZU_BENCHMARK_CLIENTS_COUNT=5 # How many clients should run in parallel during the benchmark
+```
+
+# Example output graph
+
+An example output graph from a 15 min run with 15K payload and 1000 QPS looks like
