The runner change from linux.24xl.spr-metal (bare-metal with KVM support) to 8-core-ubuntu (shared virtualized runner) will significantly impact Android emulator performance. The emulator is configured to use 6 cores and 16GB RAM (lines 122-123), and the comment at line 110 mentions 10-minute cold boot times. On a shared virtualized runner without KVM acceleration, emulator boot times and test execution could be substantially longer, potentially causing timeouts. Consider: 1) reducing the emulator-boot-timeout (line 129) if testing shows improved performance, or increasing it if timeouts occur, 2) verifying the shared runner has sufficient memory for the 16GB RAM allocation, and 3) monitoring job duration after this change.
