As I mentioned before, while a single LO process can serve multiple
clients simultaneously, and with low latency for starting a request, it
will likely struggle to fully utilise all the threads of a modern CPU.
I believe you still haven't mentioned what the specific use case you're
trying to achieve is - what are its requirements for interactiveness
and/or throughput? (i.e. is it an interactive process that will
primarily require low latency, a bulk process that requires high overall
throughput but may not mind if individual requests are delayed for a
short time, or something that requires both low request latency and high
If you need both the lowest request latency and the highest throughput
on a single machine, you may need to try adopting a hybrid model - start
a pool of independent LO instances of an appropriate size for your
number of CPU threads, then feed them jobs one at a time each. There is
definitely no canned answer for this, so you would have to do your own
benchmarking and tuning to find the optimum pool size for the resources
of your local machine.
