## Optimized when the network is unstable
By default, if there is a slow read request caused by network problems, this request will block other requests, such as writing.
Set `volume.hasSlowRead` to true,this prevents slow reads from blocking other requests,but large file read P99 latency will increase.
Increasing `volume.readBufferSize` (for example, set to `filer.maxMB` size) can make read requests require fewer locks , which can fix the P99 latency problem caused by `volume.hasSlowRead`
## Logging
When going to production, you will want to collect the logs. SeaweedFS uses glog. Here are some examples:
