-Measuring Tor's performance as users experience it
-==================================================
-
-The performance (latency and throughput) that Tor users experience depends
-on numerous factors and is the subject of current research. In order to
-evaluate progress in improving Tor's performance, we need to continuously
-measure how fast Tor really is for our users. The primary purpose of these
-measurements is to compare how performance evolves over time. This howto
-uses a trivial SOCKS client to download files of various sizes over the Tor
-network and write down how long substeps take.
-
-The following configuration parameters are used:
-
-- 50 KB file, downloaded every 5 minutes, timeout of 4:55 minutes,
-  MaxCircuitDirtiness of 1 minute, SOCKS port 9020, no entry guards
-- 1 MB file, downloaded every 30 minutes, timeout of 29:55 minutes, default
-  MaxCircuitDirtiness of 10 minutes, SOCKS port 9021, no entry guards
-- 5 MB file, downloaded every 60 minutes, timeout of 59:55 minutes, default
-  MaxCircuitDirtiness of 10 minutes, SOCKS port 9022, no entry guards
-
-Create sample files of correct sizes and make them available somewhere via
-http:
-
-$ dd if=/dev/urandom of=.50kbfile count=1 bs=50K
-$ dd if=/dev/urandom of=.1mbfile count=1 bs=1M
-$ dd if=/dev/urandom of=.5mbfile count=1 bs=5M
-
-These files are available as http://torperf.torproject.org/.50kbfile (and
-the other two file names). You may use these files, or you can use your
-own files instead.
-
-Check out and build torperf:
-
-$ svn co https://svn.torproject.org/svn/torperf/trunk ~/torperf
-$ cd ~/torperf
-$ make
-
-Create data directories for the Tor clients (every download uses its own
-Tor client) and write torrc files:
-
-$ mkdir torclient50kb
-$ mkdir torclient1mb
-$ mkdir torclient5mb
-
-$ cat <<EOF >> torclient50kb/torrc
-DataDirectory .
-SocksPort 9020
-MaxCircuitDirtiness 1 minute
-UseEntryGuards 0
-RunAsDaemon 1
-Log notice file log
-EOF
-
-$ cat <<EOF >> torclient1mb/torrc
-DataDirectory .
-SocksPort 9021
-UseEntryGuards 0
-RunAsDaemon 1
-Log notice file log
-EOF
-
-$ cat <<EOF >> torclient5mb/torrc
-DataDirectory .
-SocksPort 9022
-UseEntryGuards 0
-RunAsDaemon 1
-Log notice file log
-EOF
-
-Write a start script to start the Tor clients and execute it:
-
-$ cat <<EOF >> start-tors
-#!/bin/bash
-cd ~/torperf/torclient50kb && tor -f ~/torperf/torclient50kb/torrc
-cd ~/torperf/torclient1mb && tor -f ~/torperf/torclient1mb/torrc
-cd ~/torperf/torclient5mb && tor -f ~/torperf/torclient5mb/torrc
-EOF
-
-$ chmod a+x start-tors
-$ ./start-tors
-
-Install the timeout tool:
-
-$ sudo apt-get install timeout
-
-Add crontab entries to start the regular requests (line breaks are only for
-formatting purposes here):
-
-$ crontab -e
-
-*/5 * * * * timeout -2 295 ~/torperf/trivsocks-client
-  torperf.torproject.org 127.0.0.1:9020 /.50kbfile >> ~/torperf/50kb.data
-  2>/dev/null
-2,32 * * * * timeout -2 1795 ~/torperf/trivsocks-client
-  torperf.torproject.org 127.0.0.1:9021 /.1mbfile >> ~/torperf/1mb.data

-  torperf.torproject.org 127.0.0.1:9022 /.5mbfile >> ~/torperf/5mb.data
-  2>/dev/null
-
-From now on, the three files 50kb.data, 1mb.data, and 5mb.data should
-accumulate lines like this (50kb.data shown here; line breaks are only for
-formatting purposes):
-
-1244638801 612981
-  1244638801 612991
-  1244638801 613051
-  1244638801 613126
-  1244638801 613134
-  1244638814 282441
-  1244638814 282466
-  1244638817 164531
-  1244638826 335235
-  84 51466
-
-The column headers might be:
-
-startsec startusec
-  socketsec socketusec
-  connectsec connectusec
-  negotiatesec negotiateusec
-  requestsec requestusec
-  responsesec responseusec
-  datarequestsec datarequestusec
-  dataresponsesec dataresponseusec
-  datacompletesec datacompleteusec
-  writebytes readbytes
-
-If everything works, you might want to let your system start these Tor
-clients on system startup. On Debian, this can be done using a crontab
-entry, too:
-
-$ crontab -e
-
-@reboot ~/torperf/start-tors 2>/dev/null
