Downloads tab very slow

I've had this problem for quite a while and across multiple machines: When I go to my Downloads list (of assets already downloaded) it seems to take an absurdly long period of time to do what should be nearly instantaneous.

Other developers that I talk to don't seem to have this problem. Now - I'm kind-of an asset hog. I splurge. I buy assets all the time - I do a lot of rapid prototyping of concepts and like having a large collection of resources I can pull from instantly.

I just cleared a filter - in order to show the entire list - and I timed it. 16 seconds. If I'm coning from the Asset Store home, switching to downloads takes closer to 20-25 seconds. To bring up a list of local assets, this seems like an absurdly long period of time. (I come from a vfx pipeline architect background - so asset libraries are kind-of my thing. I have to enable searching of much larger collections of assets, across a network, on remote servers, and don't have search times like this unless it includes startup of the search tool itself or needs to rebuild the asset caches.)

Is this just me? Is it a known bug?
