Bug ID: 58749
           Summary: Delayed startup of wine processes in Wine-10.16
           Product: Wine
           Version: 10.16
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Keywords: regression, source
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: [e-mail]
          Reporter: [e-mail]

   Regression SHA1: 7bb835b3482de5e66515b5a0bd8dce8dc9844c93
      Distribution: ArchLinux

There is a noticeable delay (8-10s) when starting any applications in
Wine-10.16, e.g. wine regedit. No disk activity or high cpu usage from
wineserver can be seen with htop, there is just a delay before the actual
program appears on the screen.

Reproduced with 32bit-only, shared WOW and the new WOW64 prefixes alike.

Started happening after
commit 7bb835b3482de5e66515b5a0bd8dce8dc9844c93
ntdll: Use in-process synchronization objects.

The issue doesn't exist with the previous commit or when the ntsync kernel
module is not loaded.

I'm using Arch Linux and tested with both the current official kernel on Arch
(6.16.10-zen1-1-zen) and with kernel-6.17-cachyos-bore.

--- Comment #1 from Béla Gyebrószki  ---
I have winemenubuilder.exe disabled in my ~/.bash_profile by setting the
WINEDLLOVERRIDES variable.
Could that be the reason?
Everything starts instantly if I remove that override.

I can confirm that observation.
