Bug description:Using PharData to create TAR files is super slow (at least 10x slower)

Description:
------------
while working on one of our projects we figured creating TAR files with
PharData would be a great fit, because its php-src builtin.

it turns out though creating TAR Files with PharData is super slow,
compared to userland php implementation.

we see 10x slower performance.

see a benchmark and repro script at
https://github.com/staabm/php-phardata-benchmark

Expected result:
----------------
PharData should be at least on paar with php userland implementations

Actual result:
--------------
its slow
