        "description": "##3xsd\n3xsd is a native epoll server serving TCP/UDP connections, a high performance static web server, a\nfailover dns server, a http-based distributed file server, a load-balance proxy-cache server, and\na 'warp drive' server. Written in python, take the full power of multi-cores.\n\n##Features in detail:\n\n###3wsd - web server\n       supporting: static files, event driven(epoll), using mmap & sendfile to send files,\n       in-mem xcache, transparent gzip content transfer with fixed length(small file) & \n       chunked(large file), persistent storage of gzip files,\n       partial support of WebDAV(PUT/DELETE), pipelining support\n       \n###3nsd - dns server\n       supporting: only A record resolution, domainname failover(refer to conf file),\n       ip icmp probe & hide when fail, round robbin ip resolving\n       global DNS Left-Right Range Resolve(LRRR)(experimental)\n       \n###3zsd - proxy server\n       supporting: load balance backend servers, in-mem file caching & \n       persistent cache file storage\n\n###3fsd - distribute web file system\n       supporting: mass unlimitted file storage, easy to expand,\n       O(1) location algorithm, non-centralized, can work with standard web server(WebDAV)\n       in proxy mode, file redundancy, file persistent caching\n\n###3wdd - 'warp drive' server\n       supporting: data tunneling over UDT and tun,\n       better congestion control than TCP/UDP over wan link,\n       better thoughput(above 80%) over wan link, refer to this report:\n       http://www.c-s-a.org.cn/ch/reader/create_pdf.aspx?file_no=20091035\n       tunnel ip/mtu/txqueuelen/route define, auto create/recreate/destroy\n       encrypt packages through AES-128-ECB/CBC/CFB/CTR and Blowfish-CBC/CFB/CTR\n       tunnel on-the-fly compress with zlib/lzo, tunnel data relaying\n       route metric, routing data through different path, depending on tunnel rtt(choose the best one)\n\nMore to find in .conf file.\n\n##Performance:\n\n###3wsd:\n  Small file under 1KB single process test(full in-mem), contrast with nginx configuring\n  accept_mutex off, 80% performance.\n  Multi processes test, with reuse_port enabling kernel, 95% performance of nginx(and beyond,\n  may be 105% or more, based on process number, I tested 2-4).\n  The tests above is not quite strict\uff0c but I just want to say that it's fast enough.\n\n  And with pipelining enabled, 3wsd will perform better with 3-4 requests/send(5%-10%\n  performance increase), 2 requests/send have the same speed with non-piplining.\n\n###3zsd:\n  About 80% performance of 3wsd.\n  \n###3nsd:\n  Fast enough...about 2800-3000 queries/s per processes, with 1GHz bcm2709 4-cores ARMv7\n  cpu testing, better when multi-processes with reuse_port enabling kernel.\n  \n###3fsd:\n  Same with 3zsd.\n  \n###3wdd:\n  Early testing indicated that:\n  UDT tunnel(no encrypt) performing 50%-60% speed of direct TCP connection with ZetaTCP,\n  and package lost rate remaining below 0.6%, while direct connection has 1.4%-3%.\n  (Test CN-US WAN link with 150ms-280ms latency, through the always-jammed CUCN submarine cable)\n  However, UDT tunnel beats normal TCP connection without ZetaTCP, with 50% - 4 times\n  (commonly 1-2 times) outperforming.(v)(Test link like above)\n\n  Update:\n  And an encrypted UDT tunnel with AES-CBC/CFB will has 50% performance decrease (because the \n  method itself processes doubled size of data, and extra iv/padding data transfer).\n  Now with a Blowfish-CTR method, tunnel data transfer performance is closed to raw non-encrypt \n  tunnel. I believe that with a intel AES-NI supported CPU(like XEON E3-1240/1270), AES-128-CTR\n  can also do it.\n\n###More performance:\nThere are at lease two ways to increase the performance of 3xsd:\n\n       1.Install Cython, and rename _3xsd.py to _3xsd.pyx, run it. \n       Cython will compile _3xsd.py lib into a _3xsd.so file, using static type\n       declarations. This can gain about 5%-6% performance increasement.\n       2.Use PyPy.This can gain about 10%-15% performance increasement(or more).\n\n#OS requirement & install: \n\nCentOS 6/7 with python 2.6/2.7, Debian 6/7. Python 2.7 recommended.\n\nDoing this before running the program(minimal requirement):\n\n       yum install python-gevent pysendfile python-setproctitle python-psutil python-pip\n       \n       (python-pip is optional if install dpkt)\n  \nDpkt module is also needed when running 3nsd DNS server, pip install it.\n\nIf you want to use 3wdd, python-pytun, pyudt4, pycrypto, python-lzo are also needed.\n\n       yum install python-crypto2.6 python-lzo (for centos6)\n       yum install python2-crypto (for centos7)\n\nwill quickly install pycrypto(probably do some 'linking' works) and lzo. The other two depended on pip install.\n\nProbably you need this easy-install.pth file in python's site-packages dir:\n\n       import sys; sys.__plen = len(sys.path)\n       ./pycrypto-2.6.1-py2.6-linux-x86_64.egg\n       ./pyudt4-0.6.0-py2.6-linux-x86_64.egg\n       import sys; new=sys.path[sys.__plen:]; del sys.path[sys.__plen:]; p=getattr(sys,'__egginsert',0); sys.path[p:p]=new;          sys.__egginsert = p+len(new)\n\nI provide pre-compiled package [pyudt_tun-centos6-x86_64.tar.gz](https://github.com/zihuaye/3xsd/blob/master/pyudt_tun-centos6-x86_64.tar.gz) and [pyudt_tun_lzo-centos7-x86_64.tar.gz](https://github.com/zihuaye/3xsd/blob/master/pyudt_tun_lzo-centos7-x86_64.tar.gz) to simplify\nthe installation procedure of pyudt4 & python-pytun.\n\nBe aware of pyudt4 having some bugs, you'd better download it's source code of epoll-fixes branch and \napply the patch I offered. See changelog.txt v0.0.20  2016.03.07 fixed section for detail.\n(Already included in [pyudt_tun-centos6-x86_64.tar.gz](https://github.com/zihuaye/3xsd/blob/master/pyudt_tun-centos6-x86_64.tar.gz) and [pyudt_tun_lzo-centos7-x86_64.tar.gz](https://github.com/zihuaye/3xsd/blob/master/pyudt_tun_lzo-centos7-x86_64.tar.gz))\n\nOr, of cause you can let pip do it all for you(not including patching pyudt4):\n\n       pip install 3xsd\n\nIn a debian, you can use apt-get to install python-pip(pip) or python-setuptools(easy_install),\nthen to install the packages following.\n\nPython Packages(Modules) version reference:\n\n       gevent==0.13.8(1.0.1, 1.1)\n       greenlet==0.4.2\n       pysendfile==2.0.1\n       setproctitle==1.0.1\n       psutil==0.6.1\n       dpkt==1.6(1.8.6)\n       python-pytun==2.2.1\n       pyudt4==0.6.0(epoll-fixes branch)\n       pycrypto==2.6.1\n       python-lzo==1.8\n\nSystem libs version reference:\n\n       libevent-1.4.13-4(not actually used, just needed for gevent to function)\n       udt-4.11-6\n       lzo-2.03-3.1\n\nTo install a module of specific version(like gevent 0.13.8), you can:\n\n       pip install gevent==0.13.8\n\nThis will install the latest version of gevent(pypy will need it):\n\n       pip install git+git://github.com/surfly/gevent.git#egg=gevent\n\n",
