disabling mod_pagespeed and removing cache files

I’ve disabled mod_pagespeed for individual sites on one server to conserve disk space. Is it safe to delete the /var/cache/mod_pagespeed directory? It currently has 26 GB of files, which is more than the sites themselves use.

Thank you.

Yes, it may be deleted. You may also move to charge it per-account by setting [pagespeed] => storage_persite to True, then run upcp -sb apache/modpagespeed.
