Mathematica output that slow???

Greatings all,

I am having trouble writing to output files from Mathematica.   
Actually doing the output is trivial, but the time it takes to  
complete the operation seems quite slow.  Perhaps I should describe  
how I use the Write[] function.  Basically at the beginning of the  
program I open a file to write to with OpenWrite[].  Then my program  
carries out a couple hundred calculations and writes one line to the  
outputstream and repeats, a couple hundred more calcs and another one  
line write.  Finally, when the program is complete I Close[] the  
output file.  My problem is that in writing files that are tens of  
thousands of lines long, the process seems quite slow compared to its  
Fortran counterpart.  Is there a better way to write like this in  
Mathematica (by better I mean faster).  :)

Thanks for any help,

Kevin Towles
