We are working in a prototype app installed on a surface pro tablet. This app works against a local Oracle DB. We are using 21c express edition for Windows X64 for studying purpose. This prototype was working reasonably well while we were using architecture Windows X64. But we have another surface pro tablet with Windows 11 and ARM64 arch. Oracle 21 XE works in this tablet, but we have noticed a performance regression . Any help or advice about this situation? Someone who has faced the same issues before??. Thanks in avance.
