There is no single "best approach". If two goroutines A and B access two different indices iA and iB you do not need any synchronisation between them. If iA==iB you need to protect reads from concurrent writes. If you have far more reads than writes: Use a RWMutex, otherwise a Mutex probably is fine. The trick here: Experiment and measure. You can synchronise on the Bar-level or on the level of individual Foos. Or you can group lets say N Foos together and synchronise on the level of these groups. The trick here: Experiment and measure. So it boils down to: What is your access pattern? Make several experiments which simulate this pattern and measure. Then decide on "the best".
