I'm hoping for opinions on using an io_service per core against a single io_service with multiple threads (similar to HTTP Server examples 2 & 3). The application is a TCP authentication / proxy server, intended to use all available cores.
- The TCP streams consist of small messages (usually a few hundred bytes) which can individually be processed quickly. - Connections themselves are fairly long lasting - average around 4 hours, although occasionally up to 10-12 hours.
We're looking for a 'shared nothing' design between threads - database queries can be made per-thread (using TLS), for example.
Are database queries blocking or non-blocking? If they're blocking, won't this also block other connections handled by the same thread? Olaf
