To run this test we should use emulators.js (from emulators) and use our js-dos bundle to start the test. You can estimate performance of your device here. Js-dos bundle with this test can be found on Test page. Output is a VAX MIPS RATING which is Drhystones per second divided by 1757 (is as DEC VAX 11/780 result). Source code of the modified test is here.īasically this test produces a lot of int operations and measures the amount of operations (Dhrystones) produced per second. Drag the ROM file to the Delta Emulator window and click on Add. Click on the connected device and then open Apps ( top of the screen ) Tap the option for File Sharing and tap on Delta.

Plug your device into your computer and open iTunes. When the clock() call happened, a modified version sends ~>dtime marker to stdout which is intercepted by the test page and used to calculate delta time with performance.now() from the browser. Download the ROM for your game onto your PC. Which is good for a real pc, but is not very accurate for a dosbox emulator. Original version used clock() to calculate delta time. To measure performance we used a variant of Dhrystone 2 Test originally taken from this page. Esitmating emulators performance Performance testing #
