The International PHP Magazine has posted the results of the question asked in their latest poll - "What is the Top Criterion for Scaling PHP?"

Of the six options they provided:

• Object code caching
• Template systems
• Distributed object-caching systems
• PHP variables that can be set
• Output Compression
• Other things that may help

one stood out as a clear winner - "Object code caching". Bringing up second place was "Distributed object-caching systems" and the other options coming in pretty close behind.
