Now, during a transfer, each packet is signed and optionally encrypted. With the release of macOS 10.12 Sierra, Apple has increased the security of network shares with the more up-to-date SMB2 and SMB3 protocols. If any of the network components do not fully support jumbo frames, it is recommended to use the default MTU 1500 setting to avoid performance degradation. In the Advanced window select the „Hardware“ tab and set „Configure:“ to „Manually“. Click the „Advanced…“ button in the lower right. To set jumbo frames on macOS: access the System Preferences > Network and select the network interface. ![]() You can expect the increased throughput to result in better overall Resolve performance. When jumbo frames are enabled, one can expect an improvement in performance thanks to the fact that every network package will be able to carry more data. If every component of your network infrastructure supports it, set packet size to jumbo frames. Navigate to Preferences > System > Media Storage and turn off Direct I/O on the added mounts. In our 4K 16bit DPX export test on Mac Studio, enabling the Direct I/O feature resulted in exports that were approximately 5X slower. However, enabling Direct I/O will likely decrease performance in virtually any case. This theoretically allows access to the full performance of the drive when using Linux OS. This feature allows DaVinci Resolve to write directly to the drive using the kernel buffers, bypassing the normal storage cache in RAM. These settings can improve real-time playback performance. In DaVinci Resolve, navigate to Preferences > User > Playback Settings and check the “Hide UI overlays” and the “Minimize interface updates during playback”. The maximum and the default setting for this preference is 75 percent of your system’s RAM. To set a memory limit navigate to Preferences > Memory and GPU > System. Please keep in mind that the amount of RAM required for optimum performance depends on your workflow. It is recommended that memory allocation for DaVinci Resolve is increased to 32 GB or above. This is the lowest possible amount of RAM to get Resolve up and running. If you require a general overview of achieving better playback performance in DaVinci Resolve, head to our blog: DaVinci Resolve: 5 ways to achieve better playback performance DaVinci Resolve Settings Set Memory Usage LimitĭaVinci Resolve 18 requires at least 8 GB of system memory to run on macOS and 16 GB when using Fusion. This blog will show you how to optimise your DaVinci Resolve on Mac Studio setup for performance over an SMB connection. These include the network and client settings, as well as the application settings. ![]() To meet these requirements, every component of the setup must be optimised. The need to work with the highest possible video bitrate, often with raw codecs, makes the color grading process one of the most performance-demanding in the post-production workflow.
