+===== Benchmark with sysbench(CPU, File IO, MySQL) =====
+==== Download and Install ====
+Download:<code bash>
+wget http://downloads.mysql.com/source/sysbench-0.4.12.5.tar.gz
+</code>
+Install:<code bash>
+yum install libtool
+cd sysbench
+./autogen.sh
+./configure
+make & make install
+</code>
+==== Syntax and Basic Options ====
+  * Syntax:<code bash>
+sysbench [general-options]... --test=<test-name> [test-options]... command
+</code>
+  * Basic Options:
+==== CPU Benchmark ====
+run script below:<code bash>
+sysbench --test=cpu --cpu-max-prime=20000 run
+</code>output:<code>
+Running the test with following options:
+Number of threads: 1
+Random number generator seed is 0 and will be ignored
+Doing CPU performance benchmark
+Threads started!
+Done.
+Maximum prime number checked in CPU test: 20000
+Test execution summary:
+    total time:                          38.5596s
+    total number of events:              10000
+    total time taken by event execution: 38.5538
+    per-request statistics:
+         min:                                  3.69ms
+         avg:                                  3.86ms
+         max:                                 23.75ms
+         approx.  95 percentile:               4.44ms
+Threads fairness:
+    events (avg/stddev):           10000.0000/0.00
+    execution time (avg/stddev):   38.5538/0.00
+</code>And You see a lot of numbers, the most important of it is the total time:<code>
+total time:                          38.5596s
+</code>Of course, you must compare benchmarks across multiple systems to know what these numbers are worth.
+==== File IO Benchmark ====
+  - Step1: Prepare:<code bash>
+sysbench --test=fileio --file-total-size=5G prepare
+</code>
+  - Step2: Run benchmark<code bash>
+sysbench --test=fileio --file-total-size=5G --file-test-mode=rndrw --init-rng=on --max-time=300 --max-requests=0 run
+</code>output:<code>
+sysbench 0.4.12.5:  multi-threaded system evaluation benchmark
+Running the test with following options:
+Number of threads: 1
+Initializing random number generator from timer.
+Random number generator seed is 0 and will be ignored
+Extra file open flags: 0
+files, 40Mb each
+Gb total file size
+Block size 16Kb
+Number of random requests for random IO: 0
+Read/Write ratio for combined random IO test: 1.50
+Periodic FSYNC enabled, calling fsync() each 100 requests.
+Calling fsync() at the end of test, Enabled.
+Using synchronous I/O mode
+Doing random r/w test

+    execution time (avg/stddev):   134.9176/0.00
+</code>The important number is the Mb/sec value:<code>
+Read 10.698Gb  Written 7.132Gb  Total transferred 17.83Gb  (60.859Mb/sec)
+</code>
+  - Step3: Cleanup<code bash>
+sysbench --test=fileio --file-total-size=5G cleanup
+</code>
+==== MySQL Server Benchmark ====
+  - Step1: To measure MySQL performance, we first create a test table in the database test with 1,000,000 rows of data:<code bash>
+sysbench --test=oltp --oltp-table-size=1000000 --mysql-db=test --mysql-user=root --mysql-password=yourrootsqlpassword prepare
+</code>
+  - Step2: Afterwards, you can run the MySQL benchmark as follows:<code bash>
+sysbench --test=oltp --oltp-table-size=1000000 --mysql-db=test --mysql-user=root --mysql-password=yourrootsqlpassword --max-time=60 --oltp-read-only=on --max-requests=0 --num-threads=8 run
+</code>
+  - Step3: To clean up the system afterwards (i.e., remove the test table), run:<code bash>
+sysbench --test=oltp --mysql-db=test --mysql-user=root --mysql-password=yourrootsqlpassword cleanup
+</code>
+===== Benchmark with graphing software =====
+==== Better Cacti Templates ====
+Download: wget https://mysql-cacti-templates.googlecode.com/files/better-cacti-templates-1.1.8.tar.gz
+===== Benchmark network speed =====
+==== using speedtest ====
+  - Step1: install speedtest on linux:<code bash>
+pip install speedtest-cli
+</code>
+  - Step2: Run test<code bash>
+speedtest
+</code>
+==== network monitor with iptraf ====
+refer: http://www.tecmint.com/real-time-interactive-ip-lan-monitoring-with-iptraf-tool/
+  * Install <code bash>
+yum install iptraf
+</code>
+  * Run normal<code bash>
+iptraf
+</code>
+  * Monitor Traffic on eth0:<code bash>
+iptraf -s eth0
+</code>
+===== Benchmark File System Read Write Performance =====
+refer: http://www.slashroot.in/linux-file-system-read-write-performance-test
+==== Using dd command ====
+  * Benchmarck the speed with which **data was cached to RAM memory, not to the disk**<code bash>
+dd if=/dev/zero of=speetest bs=1M count=100
+</code>output:<code>
++0 records in
++0 records out
+104857600 bytes (105 MB) copied, 0.102163 s, 1.0 GB/s
+</code>
+  * Ask dd command to report the speed only **after the data is synced with the disk**<code bash>
+dd if=/dev/zero of=speetest bs=1M count=100 conv=fdatasync
+</code>output:<code>
++0 records in
++0 records out
+104857600 bytes (105 MB) copied, 1.12073 s, 93.6 MB/s
+</code>
+==== Using hdparm ====
+<code bash>
+hdparm -tT /dev/sdb1
+</code>output:<code>
+/dev/sdb1:
+ Timing cached reads:   12982 MB in  2.00 seconds = 6500.84 MB/sec
+ Timing buffered disk reads: 346 MB in  3.01 seconds = 115.04 MB/sec
