# Wikipedia Moving to HHVM 2015/01/07
Wikimedia Foundation is happy to report that editing Wikipedia is now twice as quick Wikimedia Blog
Wow, Wikipedia is moving to HHVM with some good performance improvements. In addition, they have listed other advantages:
- HHVM offers sophisticated observability tools, which make it easier to spot bottlenecks and identify opportunities for eliminating unnecessary work.
- HHVM offers static program analysis
This is big for both HHVM and Wikipedia and opens up new possibilities to "dissolve the invisible distinction between passive and active Wikipedia users".
