Taking the same container, having it do the same work, and having mounted the same volumes on a Linux host should not exhibit these same speed issues. With osxfs, latency is presently around 200s for most operations or 20x slower. The driver that interacts with macos' filesystem (the name escapes me atm), is notoriously slow in this context. With a classical block-based file system, this latency is typically under 10s (microseconds). If you're trying to upload a file to S3 that the container is reading off of a mounted volume, then the actual IO issue could be that it's slow to read the file contents and that can drag down the upload. This is exactly what u/binarydev was driving at by pointing out the file mount issue - which is generally the worst offender. This virtual layer will undoubtedly add overhead to the whole process. Most of the time, you notice this with file system access, but it applies to all resources, including networking. The implications of this is that there is a virtual layer between all host OS and hardware resources and the container host process. Added animated popover window to help first-time users get started.
DOCKER FOR MAC FILE SYSTEM SLOW FOR MAC
Install Docker Machine as a part of Docker for Mac install in /usr/local.
It's largely invisible to you, which makes it really handy. File system/sharing: Support inotify events so that file system events on the Mac will trigger file system activations inside Linux containers. It then issues commands to the Docker engine running within that VM from your desktop software and tooling. Slow File I/O on Container VS Host Docker 1.24 Docker for Mac 696. Since the host (Mac or Windows) lacks a functional Linux kernel, Docker Desktop actually runs a virtual machine that is a purpose built Linux distro. Usually you would Latency is the time it takes for a file system system call to.
