As others have said, it's all a matter of perspective. As an example in 
the MMO world, Dungeon Runners puts most of the logic in C++, because 
Dungeon Runners has to be as efficient with server resources as it can. 
Other MMOs with bigger budgets can afford a lower player-to-server 
ratio, and can thus afford to gain the advantages of scripting 
languages that others have mentioned: faster turnaround time, easier 
programming (especially important if you have any designers working in 
the language), etc.

Outside the MMO space, the performance of modern systems is such that 
servers don't tend to have any problems with running all the logic in a 
scripting language.

That's my two cents: in the context of MMOs on a tight budget, sticking 
to C++ is a pretty good idea.  Outside of that, I think there are 
likely to be bigger bottlenecks for your system (like the algorithms 
you're using).
