very fast stateless web server for serving dynamic pages using postgresql

[jerome lafon]

Hello,

I am looking for a very fast stateless web server for serving dynamic pages using postgresql.
In addition I will use a Key value store like REDIS for caching the HTML.
The web server doe not have to manage a context, a session or a state for each connection but it needs to be able to serve a lot of requests per second as fast as possible and if possible without the need of a lot of memory.
Currently my frontend webserver is Nginx which transfer the requests to G-WAN to serve the requests using some C code, so it's pretty fast and not consuming a lot of memory but I wanna take some information on another solution because G-GAN crashes every day at around midnight for an unknown reason. 
It's not as stable as I expect for a production web server.
I am potentially interested by vert.x, CPPSP, HipHop Virtual Machine for PHP.
I would prefer coding in C/C++ or Java or eventually in PHP.

Hi Jerome,

Given your scenario description and the languages you are comfortable with, I think the options you are evaluating sound right.

If you are comfortable developing your web application in C++, cpoll_cppsp is presently king of the hill in our performance tests.  I personally don't trust my C++ skills sufficiently to tackle such a challenge, but it sounds as if you are up to it.

On the Java side, you can't go wrong with a Netty-based framework like Vert.x.  That said, you may also want to take a look at Undertow, the new web server that will be the basis of WildFly, which is JBoss Application Server 8.  I am quite fond of the Undertow native API—it's fluent, clean, brief (for Java), and easy for me to understand.

We don't yet have performance measurements for HipHop+PHP.  I am optimistic that we'll eventually receive a pull request that includes HipHop, but for the time being that remains an unknown to me.  I have no reason to doubt Facebook's claims, but I'd like to be able to see how it stacks up in our tests.

I hope this helps!

Thank you for your reply.

CPPSP seems to be a good option for me.

I have already coded in C for G-WAN so I would have to adapt my code but the logical part is already defined.

What does it mean cpoll_cppsp? Is it a way to implement the web server application?

Do you think CPPSP isenough mature to be use in production?

Otherwise vert.x seems very promising also and perhaps a little bit more mature but I believe the memory usage will be really bigger than with a C/C++ server.

Hi Jerome,

I personally have not used CPPSP (as I implied earlier).  But the developer has contributed here in the past and I believe he would consider it production-ready.  I leave it to you and others to debate whether you feel it's sufficiently production-ready for your use-case.

In terms of adoption, something like Vert.x has seen a modest amount of production usage.  Popularity-wise, I would say it's a second-tier framework (where first-tier are easily recognizable names like Rails, Django, and Spring).  Second-tier may be a sweet-spot.  It means there is enough community support to help you through tough spots but there's not as much history and cruft to weigh down the framework.

Memory usage of a Java application server will most likely be greater than a decently-tuned C++ application.  I'm not sure what kind of memory constraints you have, however.  Are you working with several gigabytes of data?  If not, I'm not sure the memory situation is worth worrying about.

[jerome lafon]

Thanks for your very interesting reply.

I care about memory usage because I use only one VM for hosting all the application (nginx, php, postgresql, g-wan, REDIS...).

Later I will separate these applications on several servers but currently I don't.

I just discovered openresty which seems very promising. Do you have any feedback on it?

Jerome

OpenResty easy to learn and build on projects. One limitation is I have to stop and restart OpenResty each time I made changes to the Lua code, not sure if that was the way instead of hot reload. If that is, this will definitely slow down our productivity significantly.

Hello Brian,
I am not a web developer neather software engeneer but I have some project in implementing C++ in my magento shoping cart code for better performance and wanted to use cpoll_cppsp,
my question is; is cpoll_cppsp just a webserver just like HipHop+PHP or is it a webserver and a code to implement, integrate inside a php application???

As I want to customise my magento extensions from php tp c++ I am more kind of intrested to use cpoll_cppsp in my php code such as for a lybrary for instance rather then using a web server,
could you please clarify the points above,
regards, Heather
