High performance impact even when MCP server is off

[johnkslg]

I'm seeing spikes of 28ms every one second, it looks like a ton of allocations happening. Makes my game hitch. Should at least turn off when mcp is off, as is I have to uninstall the package to remove that hitch.

Im having the exact same issue, the game will stutter every second, even during editing mode, while dragging windows around or moving objects in the scene. Removing the mcp package eliminates the hiccups.

@msanatan @dsarno definitely something need to look at.

Yes reviewing the PR and will resolve tomorrow.

@thomaswilliams02948 @johnkslg Can you try again, making sure you are using latest MCP for Unity version (v9.0.8)? I put in a fix for this hitch like a week ago (#556), and have not been able to reproduce your profiler results in latest releases (at least on Mac -- haven't done full testing on Windows).

Ok this is actually a separate hitch from the UI-related one I fixed, and the one addressed in #579. This has to do with the frequency that the Editor State cache is grabbed. I have a fix for this, may have to wait to tomorrow. Thanks for flagging this all.
