I am experiencing a slow down rendering a large table report:

The table report is more than 240 lines. Reading at the source html, it
is about 900 bytes per lines, so a bit more than 200kB for the report.
Not much for the rest of the page. The page renders in a bit more 5s, on
a local loop.
Profiling shows most of time is spent in WideString>>at:put:

For me 200KB is not that big and this slow down does not look normal.

Seaisde is
Smalltalk is Pharo3
CPU is double core intel 800Mhz-2000Mhz
VM is 3.9-7   

The profiling tree is as shown in the screenshot.
