Whats App Group chat

 It took us slightly longer, but group chat is finally here.  If you have an iPhone, BlackBerry or Android phone, simply upgrade to version 2.6 of our software to enjoy group chat.  If you have a Nokia Symbian S60 phone, we are working on adding group chat to our Symbian client and hope to release it shortly.
Here are a few important notes on group chat:

• currently group chat is limited to 5 people.  in the future we will increase this limit.
• you can exit a group chat that you are in at any time.  simply delete the group conversation from the main Chats window to do that.
• you can control group chat alerts and notifications separately from individual messages.

we are continuing to work on adding more cool group chat features and fixing bugs...  if you have any group chat feedback, let us know.

Whats App Nokia S40

Today we are happy to announce the public beta release of WhatsApp Messenger for the Nokia S40 platform. You can download it by visiting http://www.whatsapp.com/s40/ from your Nokia S40 phone (we are only supporting Nokia C3-00 and Nokia X2-01 phones at the moment, but we plan to add support for more S40 devices in the future)

As with any beta software, we need your help finding and reporting bugs - so please email s40-support at whatsapp dot com if you run into any problems with WhatsApp Messenger on your Nokia S40 phone. You can also contact us directly from the app via Options > About > Contact (that is preferred method when reporting bugs)

Please keep in mind that the product is still in beta and has limited functionality when it comes to multi-media or group chat. We plan to continue development efforts to further improve the application by fixing existing bugs and adding new features. Stay tuned...

Whats App ONE MILLION!

We usually don't use this blog to talk about the technology stack behind WhatsApp, but today we wanted to share with you an awesome milestone we have reached.
Over the past few months we have been making a lot of improvements to our servers to increase the performance, uptime and scalability. Today we have tuned some knobs, shifted some traffic around and achieved 1 million established tcp sessions on a single machine (and with memory and cpu to spare!)
$ netstat -an | grep -c EST 1016313
We are extremely proud of this achievement and wanted to share with other tech minded people out there. For those curious how we did it, the technology on the backend is simple: FreeBSD + Erlang
P.S. - we are hiring in both client and server teams, so send your resume to jobs at whatsapp dot com if you are interested.

Whats App one billion messages

Coinciding with our planet crossing the 7 billion population mark this week, last week WhatsApp crossed its own milestone for the first time by sending just over 1 billion messages in a single day.  Similar to the awe we feel that our planet will now hold over 7 billion people, all of us at WhatsApp are extremely humbled and excited about the future.
Just how much is 1 billion messages? That is 41,666,667 messages an hour, 694,444 messages a minute, and 11,574 messages a second.
1 billion messages a day is a significant milestone and also a small step closer towards our goal: providing a great mobile messaging system for a global market, regardless of your handset.
The loyalty and passion consumers have for our product leaves us feeling great gratitude, we really couldn't do it without you.

Whats App 1 million is so 2016

Happy 2012 everyone!
A few months ago we published a blog post that talked about our servers doing 1 million tcp connections on a single box: http://blog.whatsapp.com/?p=170

Today we have an update for those keeping score at home: we are now able to easily push our systems to over 2 million tcp connections!
jkb@c123$ sysctl kern.ipc.numopensockets kern.ipc.numopensockets: 2277845
Best part is that we are able to do it with plenty of CPU and memory to spare and do it sustainably:
CPU: 37.9% user,  0.0% nice, 13.6% system,  6.6% interrupt, 41.9% idle Mem: 35G Active, 14G Inact, 18G Wired, 4K Cache, 9838M Buf, 27G Free
This time we also wanted to share some more technical details with you about hardware, OS and software:

hw.machine: amd64 hw.model: Intel(R) Xeon(R) CPU X5675 @ 3.07GHz hw.ncpu: 24 hw.physmem: 103062118400 hw.usermem: 100556451840
jkb@c123$ uname -rps FreeBSD 8.2-STABLE amd64 jkb@c123$ cat /boot/loader.conf.local boot_verbose="" kern.hwpmc.nbuffers=32 kern.hwpmc.nsamples=64 kern.ipc.maxsockets=2400000 kern.maxfiles=3000000 kern.maxfilesperproc=2700000 kern.maxproc=16384 kern.timecounter.smp_tsc=1 net.inet.tcp.tcbhashsize=524288 net.inet.tcp.hostcache.hashsize=4096 net.inet.tcp.hostcache.cachelimit=131072 net.inet.tcp.hostcache.bucketlimit=120
and the last important piece of our infrastracture is Erlang:
8> erlang:system_info(system_version). "Erlang R14B03 (erts-5.8.4) [source] [64-bit] [smp:24:24] [rq:24] [async-threads:0] [kernel-poll:false]\n"
