Dear all,
At Julia site ( they placed the results 
of a battery of small performance tests. The test scripts
are referenced in the citation below:

we’ve written a small set of micro-benchmarks in a variety of
 languages:  C Fortran Julia Python Matlab/Octave R JavaScript Java Lua Go , and  Mathematica .
I began to translate R code into gretl to do the same battery
of tests for Gretl. The script attached.
The firs test is about recursion: compute
Fibonacci numbers.
Either, I wrote very inefficient code, or
recursion in Gretl is very slow and needs amending.
The attachment also contains non-recursive script
for Fibonacci numbers. It works several thousands
 times faster ( 172092 times on my pc) .
