<PRE>Hello !
Today I have found very interesting library from SGI
(<A HREF="http://oss.sgi.com/projects/state-threads/">http://oss.sgi.com/projects/state-threads/</A>)
It's based on Netscape Portable Runtime library (NSPR)
and amed on creating high perfomance network applications.
Look at documentation
(<A HREF="http://oss.sgi.com/projects/state-threads/docs/st.html">http://oss.sgi.com/projects/state-threads/docs/st.html</A>)
><i>From documentation:
</I>
It is contained in 8 source files as opposed to more than 400, but
provides all the
functionality that is needed to write efficient IAs on UNIX-like
platforms.
NSPR State Threads
Lines of code ~150,000 ~3000
Dynamic library size
(debug version)
IRIX ~700 KB ~60 KB
Linux ~900 KB ~70 KB
State Threads is an application library which provides a foundation for
writing Internet Applications. To summarize, it has the following
advantages:
It allows the design of fast and highly scalable applications. An
application will scale well with both load and number of CPUs.
It greatly simplifies application programming and debugging
because, as a rule, no mutual exclusion locking is necessary and the
entire application is free to use static variables and non-reentrant
library functions.
The library's main limitation:
All I/O operations on sockets must use the State Thread library's
I/O functions because only those functions perform thread scheduling and
prevent the application's
processes from blocking.
I'm just wonder, what is the implimenantion design of NeL server-side
according to the above document ?
