--- Comment #8 from Pavel <klev.paul at gmail.com> ---
HTML::ScanText (svtools/source/svhtml/parthhtml) reads html token data up to
MAX_LEN (=1024) symbols to temp buffer and then do concatenation (+=) of
strings.
This causes allocation of memory and copying existing data and new data
(memcpy)
And because number of chunks is substantial, copying of almost the same data is
repeated multiple times

Possible solution could be increase buffer size each time it is filled (1024,
2048, 4096...)
