Firefox causes delay in updating textarea with huge data.

[shar_chan]

Hi Guys,
In Firefox, filling text area with huge data causes some seconds delay depending upon the size of the information.

I have got text area in my hetml page like this
<textarea id="log"></textarea>

When i update the text area from java script code after receiving the info from SOAP response, it is causing more thn 20 seconds delay..
document.getElementById('log').value = log_info;

The problem doesn't persists in IE or Mozilla.
Any idea on this
