What is the fastest/best way to show Thumbnail view in TC ?

[Kyles]

1. Default setting, enable the following options,
Thumbnail view speed is fast, but still slower than Windows Explorer, even the TC cache is enable.
v Database location %$LOCAL_APPDATA%\GHISLER
v Get from Lister plugins for *.*
v Use Explorer method (OLE2) for: *.* | *.htm *.html
v Get from Irfan-/Xnview for *.*
v Plain text file thumbnails for *.txt *.ini

2. Once added some plugin for Lister, if not disable the "Get from Lister plugins for *.*" option,
Thumbnail view speed is much slower...

3. Install wlx_htmlview v1.2.6 plugin, and then in Quick View mode to select a directory,
Thumbnail view speed is very fast, and it can use Ctrl + Mouse wheel to zoom in/out the Thumbnail view size directly.
But wlx_htmlview can NOT use F2-rename / Del-delete... shortcut keys, only the right click-context menu is available.

Is there any faster/better way?
