How many threads a server can handle?
Each processor has 10 cores, each core being basically equivalent to a classic single-core CPU on its own. Each core can only run 1 thread at a time, i.e. hyperthreading is disabled. So, you can have a total maximum of 20 threads executing in parallel, one thread per CPU/core.
Why can a core have 2 threads?
To have >2 “threads” per core, you’d need more resources, taking up more space. Core = mouth. Data to process = food. The hands can bring food to your mouth, but you only have one mouth – the second hand is ready to go as soon as the mouth is free.
Is 4 threads per core possible?
The 4 threads per core processors would be perfect for the data center and HPC markets, and would pave the way for gigantic performance improvements from all those threads. 4 cores per thread isn’t exactly new, with IBM supporting it with its Power CPU architecture supporting a huge 8 execution threads per core.
What are the advantages of a multi-threaded chat server?
This is exactly the situation with a chat server. The main advantage of asynchronous technology is that since there is only one thread, then by definition, the server only does one thing at a time. So, all of the issues associated with synchronizing access to shared data between multiple threads disappears.
How are timeouts used in a multi-threaded chat server?
Since the client only manages one socket, the use of timeouts to facilitate the multi-tasking is a good solution. Since the objective of this activity was to develop a multi-threaded chat server, the approach of using timeouts was also adopted for the initial implementation of the server.
Is there a limit to how many threads you can use?
There are two factors that affect how many threads you should allow for. The first is the number of DB connections available. This may be a hard limit unless you can increase it at the DBMS – I’m going to assume your DBMS can take an unlimited number of connections in this case (although you should ideally be measuring that as well).
How does a child thread work in a chat server?
When a connection is received, a child thread is started and it waits on the socket.recv () call until data is received and then it collects the response needed, perhaps via a data base query, and returns the results to the client.
