hello,
1. Yes. Load depends on your application. Simple requests are handled
within a milisecond, but it really depends on what the handling of those
events takes. Same goes for memory consumption
2. There are many strategies. You can avoid the impact of an application by
a good support for URLs, so that a full reload of the session (which
happens when you'd restart a server) would put you back in the application
where you were. This would be mostly similar to what you get with other
frameworks. You can also use a reverse proxy that forwards sessions
depending on some prefix in the session ID, and deploy the new applciation
with a different session prefix, and configure your reverse proxy that new
sessions go to one instance while the old sessions are still served by the
old instance (e.g. by running them on separate ports). When there are no
sessions left in the old instance, you can kill it.
3. afaik Wt::Dbo has no features for automatic database migration. You will
have to run your migration scripts manually.
4. There's Wt's WTestEnvironment, or what kind of tests are you looking for?
BR,
Wim.
