Comparing the performance of Jace.NET and NCalc

I started the development on Jace because I wanted to develop a high performing mathematical formula execution engine that worked on all the major Microsoft platforms (.NET, Windows RT, Windows Phone 7.5 and Windows Phone 8). Jace was not the first such framework, other calculation engines existed already; like for example NCalc. Unfortunately, to my knowledge no engine was available that also supported newer platforms like Windows RT or Windows Phone.

I decided to compare the performance of Jace with an important competitor: NCalc. I downloaded NCalc and Jace 0.7 using NuGet. Both engines were used with the default settings and were given the same 10 random generated formulas with 3 variables. Each function was executed “n” times with random input.

The graph below clearly shows that Jace.NET greatly outperforms NCalc. The x-axis is showing the total number of formulas executed and the y-axis the total time in milliseconds.

Benchmark Jace.NET vs. NCalc (time in ms.)

As the developer behind Jace, I am very happy to notice that the time I have spent on the dynamic compiler of Jace is paying off. It is responsible for the high performance of execution. This dynamic compiler is available on all platforms Jace supports (.NET, Windows RT, Windows Phone 7.5 and Windows Phone 8) and it is the default setting.

The source of the application used for the benchmark can be found at:

    Hi, performance seems good but jace is thread safe ?

      yes, Jace is completely thread safe.

    Sure yours is faster, but yours cannot handle string and Ncalc can…

      Could you explain me for which cases you need to handle strings? If you have a valid case, I can add this functionality into Jace

        That could be great; I have been looking for a mini scripting language / Evaluator for my app, and yours was the best candidate, but since it could not handle String input and output, I had to choose JInt for C#.

        The scripting language would have access to a Class that have some methods that’s takes input and output as string. After all yours are the best on the “market”. Sincerely Anton Christiansen.
