Will wandb slow down my training?

W&B has a minimal impact on training performance under normal usage conditions. Normal use includes logging at a rate of less than once per second and limiting data to a few megabytes per step. W&B operates in a separate process with non-blocking function calls, so brief network outages or intermittent disk read/write issues don’t disrupt performance. However, excessive logging of large data volumes can lead to disk I/O issues. For more information, contact support.
