Profile loading speed

Measure and optimize how fast your data is being loaded, improving efficiency.

The StreamingDataLoader supports profiling of your data loading process. Simply use the profile_batches argument to specify the number of batches you want to profile:

from litdata import StreamingDataset, StreamingDataLoader

StreamingDataLoader(..., profile_batches=5)

This generates a Chrome trace called result.json. Then, visualize this trace by opening Chrome browser at the chrome://tracing URL and load the trace inside.
