Research direction
Start at the viewer's Connect button and reproduce the reported 12–15 second load for a 1 GiB dataset over NFS, comparing it with local storage. Measure the time until data first appears and identify whether the delay is in connection, remote dataset loading, or initial rendering; done means the initial display meets the reported two-second expectation or the bottleneck is documented.

What happened?
Hi team, I'm actively using lance data viewer in my daily work. I found when loading dataset from remote storage like NFS, the latency is significantly high.
For example, I ran the viewer in San Jose, when hitting the "connect" button to load a 1GiB dataset at Phoenix, it usually takes me 12-15 seconds to see data showing up.
Expected behavior
I expect the initial connect and display to be lightweight, and should't take more than 2 seconds.
