[Cppcms-users] Can Cppcms fully work asynchronously?

[redred77 <red...@gm...>]

I have some questions about cppcms. I'm interested about building new
project with Cppcms but not familiar with it yet and I want to know in
detail.


1. Can cppcms run multiple threads asynchronously?
I know it can handle asynchronous requests by event loop but can it be run
with thread pool and run several requests simultaneously? Or the thread
pool is only for synchronous jobs.


2. Can Cppdb handle asynchronous query?
I mean that providing callback at query execution and be called later when
query is finished. Maybe this must be handled with cppcms event loop.
Is there any example using asynchronous query or it's not possible?


3. What is the difference between running cppcms as multi process mode
beside running only single process mode?
I found that on windows platform it can't be run as multi process mode. I'm
not going to run it on windows for production but is there any other big
difference I have to aware? Something like local cache is shared between
threads but not shared between processes. Or some performance effect like
running 8 processes with single thread mode, or running 1 process with 8
threads. Information about Internal structure about performance would be
helpful.


4. Dynamic loading .so files
I saw that cppcms highly recommend to use dynamic loading views but I also
found that auto update (checking .so file's modification date and auto
reloading views) function may affect bad performance. So, dynamic loading
views are only good with test mode and static library loading is better for
production service?
I'm only asking at the aspect of performance. Loading all .so files at
startup looks much better for performance. I'm about to load more than 100
.so view files.


Thanks in advance.
Cppcms looks like well designed and implemented.
