This is a known issue when there is a large amount of data or projects in Phoenix; slow loading is often caused by heavy queries, large trace/span counts, or large attribute payloads (e.g., base64-encoded images). Recent Phoenix versions have improved performance by reducing page size, lazy loading data, and optimizing queries, but slowness can still occur with very large datasets or multimodal data. Upgrading to the latest Phoenix version and ensuring you are not storing large base64-encoded values in spans can help; a fix for image payloads is in progress and will be configurable soon. For now, waiting for the page to load or reducing the data size may be necessary (source 1), (source 2), (source 3).If you are using a self-hosted or older version, consider upgrading to benefit from these optimizations. If the problem persists, check for large or binary data in your spans and try to avoid storing them until official image support is released (source 4), (source 5).Would you like more detail or troubleshooting steps?Sources: - https://github.com/Arize-ai/phoenix/issues/4006 - https://github.com/Arize-ai/phoenix/issues/6201 - https://arize-ai.slack.com/archives/C04R3GXC8HK/p1721403303.365439 - https://github.com/Arize-ai/phoenix/issues/3917 - (source 5)

If you tell me the right answer to this question, I'll make sure I don't make the same mistake twice!
