Math::BigInt::FastCalc can help avoid the glacial speed of
vanilla Math::BigInt::Calc. Recent versions of Math::BigInt will
automatically use ::FastCalc in place of ::Calc when available.
Other options include ::GMP or ::Pari, which however have much
larger dependencies.

Then thereâs Math::BigInt::Lite, which uses native Perl integer
operations as long as Perl integers have sufficient range, and
upgrades itself to Math::BigInt when Perl integers would
overflow. This must be used in place of Math::BigInt.

Finally, thereâs the bigint/bignum/bigfloat pragmata, which
automatically load the corresponding Math:: modules and which
will autobox constants. bignum/bigint will automatically use
::Lite if itâs available.

So yeah, anyway. The point is, vanilla ::BigInt is cosmologically
slow, but with just a moment taken to install another module or
two you can get much better speed for zero programming effort.

This should go somewhere into the GStreamer POD (not necessarily
in as much detail as I went into), because not everyoneâs going
to know about it.
