Hi

The new code to generate static cache is a bit slower and consume more memory.
than before.

Flushing the cache of a folder with 30 nodes take more than 1s and generate more than 2000 mysql queries.

First issue:
In the file kernel/classes/ezstaticcache.php function storeCache
following code
foreach ( $this->cachedSiteAccesses as $cachedSiteAccess )
$dirs[] = $this->buildCacheDirPath( $cachedSiteAccess );
can be replace with
if(!isset( $this->dirs) )

{ foreach ( $this->cachedSiteAccesses as $cachedSiteAccess ) $dirs[] = $this->buildCacheDirPath( $cachedSiteAccess ); $this->dirs= $dirs; }

It will reduce the total time from 1s to 0.5s for the same result (I hope)
