It appears as if you need a faster computer.  The infinite 
loop is taking too long.  With a fast enough computer, I 
hear that an infinite loop can be completed in under 10 
seconds, so you must need to upgrade.


More seriously, in a word -- No.

It should take seconds unless your data file is huge.

If a few tens of records, milliseconds or microseconds. 

It's not obvious to me from you code what the problem is.  I 
would suspect one of two things.

You are misusing the call.  Don't know how, but I would put 
my money on this one.

You have found a bug in the library.  Not at all unlikely, 
but not the way to bet until you have tried some of the 
code examples and recreated the bug based on them.

Might be a bad build of the libraries, but not the way I 
would bet till other things seemed ruled out.
