We note that while FreeBSD and Windows actually have superior asynchronous IO support, we simply haven't ported to those within Construct yet and this section will be updated. On Linux, there are incremental benefits which Construct takes advantage of between Linux 4.4 and Linux 5.3. Always use the newest possible kernel for best performance.
