This could be problematic given that Docker disk performance on macOS was already dreadful on intel machines.Ever since Docker for Mac was released, shared volume performance has been a major pain point. Disk flushes are particularly slow due to the need to guarantee data is written to stable storage on the host. > Some container disk I/O is much slower than expected.From my perspective, the biggest is performance. Unfortunately, I use it on Mac, and it has some big drawbacks. It has a lot of advantages and I have been using it very actively for some time.
Docker Volume Performance Code Change WithTakes less than 100ms to pick up a code change with a Docker volume. Tell us about your request Integrate the mutagen pluggin within Docker Desktop to provide users with a file caching option to improve performance on modern web frameworks. This post is about volumes cachings methods – we can use them to speed up Docker in any platform and should be used, if we can do this.Ask questions Docker Desktop Improve Mac File system performance Update: we are now looking at using GRPCFuse rather than mutagen as a simpler path for perf improvement. It’s ok and necessary, but always causes some performance degradation, especially on networking and any I/O operations.It means, it’s also performance degradation, especially on Windows and Mac (it can work much better on Linux with native kernel and many system files). But, it’s I/O, sometimes light, sometimes heavy and intensive. There are plenty of use cases for volumes. We use a lot of volumes typically – to share config, to share code, to provide backups, to link some resources. In situations such as NFS asynchronous mode, if a running container with a delegated bind mount crashes, then writes may be lost. For directories mounted with delegated the container’s view of the file system is authoritative, and writes performed by containers may not be immediately reflected on the host file system. According to official Docker documentation (April 2020): DelegatedThe delegated configuration provides the weakest set of guarantees. These two methods are “cached” and “delegated”. ![]() Why? Because read-only is mostly on containers side, and we make a lot of writes from host. In this scenario, the best option is to use “cached” method. Containers will make and see all changes immediately, for host is not important and we can skip that.Second case is when we modify code frequently on host and read these changes on our containers. The best option here is “delegated”. Maybe we want backup this data? It’s read-only operation, we will not do any changes from host perspective, so we don’t need to reflect them on containers.
