That's surprisingly slow. Running the ARM emulator under Linux yields at least a couple of key presses per second in the SMS app. Admittedly I'm using a pretty fast machine but a 20x slow-downs seems excessive. It's possible that running the qemu's emulation code within VMWare is triggering some particularly slow code-paths or something. > Q: Any plans to make emulator-based B2G development a bit more realistic? > I'm only interested in the platform stuff so I can't use the simulator. You should try running it on a native Linux installation. I use the emulator quite frequently for development and we even run entire test-suites on it. It's slower than an actual phone but not *that* slow. > Q: Would a standalone box like Dell's XPS 13 with Ubuntu + i7 + 8G RAM and > SSD be useful? The emulator speed is almost entirely limited by single-threaded performance so the faster box you can buy the better but don't expect miracles from it. I'd try running it natively first and contemplate an upgrade only if that's still too slow. Gabriele
