The reason to set to a value is to set the buffer size -- and usually you do this to tune interaction between PHP and Apache and/or the underlying OS. You want to set it to a value that matches Apache's buffer size and/or the OS's network buffer size. If you don't know these, using the defaults is probably the best bet. -- Matthew Weier O'Phinney | WEBSITES: Webmaster and IT Specialist | http://www.garden.org National Gardening Association | http://www.kidsgardening.com 802-863-5251 x156 | http://nationalgardenmonth.org mailto:matthew@garden.org | http://vermontbotanical.org
