As with Zend Framework 1.8 a default caching was added. The reason behind this
change was, that most users had performance problems but did not add caching at
all. As the I18n core is a bottleneck when no caching is used we decided to add
a default caching when no cache has been set to Zend_Locale.
Sometimes it is still wanted to prevent caching at all even if this decreases
performance. To do so you can simply disable caching by using the
disableCache() method.
