I am talking about content caching, not opcode caching. If you have a page with contents do change frequently, you can use content caching (files, memcached, etc). Then PHP execution speed will be mostly irrelevant because your script will be waiting most of the time for I/O operations copying data from cache files or memcached server and the user computer. > --- On *Fri, 2/26/10, Manuel Lemos /<mlemos@xxxxxxx>/* wrote: > > > From: Manuel Lemos <mlemos@xxxxxxx> > Subject: Re: HipHop and other PHP compiler performance evaluation > To: "Raymond Irving" <xwisdom@xxxxxxxxx> > Cc: "PHP List" <php-general@xxxxxxxxxxxxx> > Date: Friday, February 26, 2010, 12:52 AM > > Hello Raymond, > > on 02/25/2010 11:34 PM Raymond Irving said the following: > > > > Very nice article.
