> Hello,
> I am benching Shiro, tahnks this method:
> public void bench() {
> final Subject subject = SecurityUtils.getSubject();
> subject.login(new UsernamePasswordToken(LOGIN+i, PWD));
> for (int ind = 0; ind < 100000; ind++) { // a lot of authorizations
> assertTrue(subject.isPermitted("medias:album:read"));
> }
> subject.logout();
> }
> I see that I waste my time in the methode WildCardPermissionResolver which
> create a new instance of permission each time even if it is the same String
> in parameter.
> I added a map which allows to cache WildcardPermission.
> You can find in attachement the patch.
> PS : the cache for authorisation is activated:
> cacheManager = org.apache.shiro.cache.MemoryConstrainedCacheManager
> securityManager.cacheManager = $cacheManager
> Regards,
> Thibault
