--- Comment #1 from V Stuart Foote <vstuart.foote at utsa.edu> ---
Can not confirm on Windows 10 Home x64 (1803) with SSD at 1920x1080
Version: 6.1.3.1 (x64)
Build ID: a9670562c26181ec3afbe381c9ff499ae88c98b7
CPU threads: 4; OS: Windows 10.0; UI render: GL; 
Locale: en-US (en_US); Calc: CL

Existing LO user profile created and present in %AppData%,
Quickstart "feature" is not enabled (i.e. a LO soffice.bin is not started at
startup/login).  A cold start of LibreOffice taks ~2 seconds to StartCenter.

Closing, and later reopening seems slightly faster, but certainly usable
without the Quickstart instance.

Starting without a user profile, same system, initial LO launch after startup
~6 seconds (has to build profile), with subsequent launch ~2 seconds to
StartCenter.

So some need info...

1. Any LO extensions other than bundled installed?

2. Any "data" source(s) in use (for form filling, maillists, ODBs)?

3. How many documents are on your StartCenter panel? Thumbnail for each must be
extracted from registrymodification.xcu in LO profile and rendered to bitmap
for display?

4. Any improvement if you delete/rename your user profile and retest?

5. How many fonts are loaded, test system above has 311, each font must be
"parsed" for inclusion in drop lists in the UI--not sure, but imagine this
happens just on initial LO launch after computer startup? Improve if you reduce
and retest?

6. Are you operating on a HiDPI monitor, small 4K display (so all LO theme
Icons would have to be unzipped from PNG and scaled larger to cache)? Can you
check on a lower resolution monitor, or change the resolution?
