What do you think is causing the significant differences in ArrayBufferContents between v2.10.0 and v3.2.1?

After upgrading from v2.10.0 to v3.2.1 in Perspective, I conducted performance measurements using Playwright to evaluate the creation processes of multiple tables and views. During these tests, I noticed significant differences in the ArrayBufferContents metric under cdpSession between the two versions.

While the periodic fluctuations are expected due to the nature of the creation processes, the overall values for v3.2.1 (yellow) are significantly higher compared to v2.10.0 (green). Despite this, I haven’t observed any noticeable performance issues so far.

However, the higher values in v3.2.1 have sparked the curiosity, as understanding the cause of this difference could help better grasp the changes introduced between the two versions. Specifically, I’m curious about:

1. What might be driving these substantial differences in ArrayBufferContents between the two versions?
2. Are there any changes in memory management or buffer allocation in v3.2.1 that could explain this?

If anyone has insights or has observed similar behavior, I would appreciate your thoughts and suggestions.

I also noticed the presence of a free() method in the documentation. While I couldn’t find detailed information about its usage, the fact that it’s exposed to users suggests it might serve a specific purpose. Could it be necessary to use free() in some way to optimize memory consumption or reduce the higher values seen in v3.2.1?
