# Wiretap Playback Speed

Regarding clip playback speed, network bandwidth and traffic play the expected role. On an optimized GigE network, for example, you can achieve up to 80 MB/sec throughput. This is enough for real-time playback of SD clips, or about 1/4 real-time for 2K material. Better results can be achieved using InfiniBand or 10 GigE. Note that the Visual Effects and Finishing application on the Wiretap server host workstation can also affect performance. Visual Effects and Finishing applications have guaranteed access to the 'local' framestores—remote access by Lustre over Wiretap is at a lower priority. If you notice playback is suffering, consider generating local proxies for the remote material.

NoteTo improve real-time playback of RED media, the Wiretap Gateway can spawn multiple slave processes that increase performance without requiring additional licenses. See the Wiretap Gateway Installation Guide.
