Bug ID: 40044
           Summary: Wine prefix creation is really slow
           Product: Wine
           Version: 1.8
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

This pretty much says it all:

$ time WINEPREFIX=$(pwd)/tmpprefix wine echo
wine: created the configuration directory '/home/r/Desktop/tmpprefix'
Could not load wine-gecko. HTML rendering will be disabled.
Could not load wine-gecko. HTML rendering will be disabled.
wine: configuration in '/home/r/Desktop/tmpprefix' has been updated.
wine: cannot find L"C:\windows\system32\echo.exe"

real    2m3.599s
user    0m0.004s
sys    0m0.008s

This is on a system with 8GB RAM, a dual-core (four threads) CPU and a fast
SSD. I don't know what takes it so long, but the time certainly seems excessive
for creating a directory of 38 MiB. This hasn't always been that slow, but it's
been slow for at least two years now.
