Performance issue with SQL Developer 24.3 on Windows Server

Performance issue with SQL Developer 24.3 on Windows Server…

Startup times on a HPE DL 360 Gen10 Plus Server (Xeon Platinum 8358, 512GB RAM):

OS: Windows Server 2025

SQL Developer 23.1.1 → 13 seconds
SQL Developer 24.3.1 → ~4min

When I add the following options to product.conf

AddVMOption -XX:+UnlockDiagnosticVMOptions
AddVMOption -XX:TieredStopAtLevel=2

Startup time of SQL Developer 24.3.1 is reduced to ~45 seconds again on this machine.

I tried it on some other machines as well: (startup times for 24.3.1)

HP EliteBook 830 G10 (Windows 11 24H2): ~20 seconds
HPE DL 365 Gen11 (Windows Server 2022): 1:25min (AMD Epyc 7313 , 128GB)
HPE DL 360 Gen10 Plus (Windows Server 2025): 4:05min (Xeon Platinum 8358, 512GB)
HPE DL 360 Gen10 Plus (Windows Server 2025): 2:39min (Xeon Gold 6342, 128 GB)
