Currently, on every request PageRouter::matchRequest collects all slug candidates and chooses the best candidate. Depending on the amount of records in the database, this may lead to a lot of queries.

For a route that has been resolved previously, the result might get cached for faster resolving. This needs a proper concept in terms of cache invalidation.

Hey Andy,

where exactly are the multiple DB queries located?

AFAIK getPagesFromDatabaseForCandidates() does only one query per language. If workspaces are enabled, we have more, of course.

We have the performance problem currently in an installation with 1600 domains too. In our case we fixed it by extending the query in the getPagesFromDatabaseForCandidates, so that only the pages of the current rootline are returned. But I'm not sure if there could be problems with mountpoints?

Changes in PageRouter.php line 334 and below

     * Get all uids below given page uid
     * @param $pageUID
     * @return string

    private function getRecursivePageUIDs($pageUID)
        $depth = 999999;
        $queryGenerator = GeneralUtility::makeInstance('TYPO3\\CMS\\Core\\Database\\QueryGenerator');
        $rGetTreeList = $queryGenerator->getTreeList($pageUID, $depth, 0, 1);
        //Will be a string
        return explode(',', $rGetTreeList);


     * Check for records in the database which matches one of the slug candidates.
     * @param array $slugCandidates
     * @param int $languageId
     * @return array
    protected function getPagesFromDatabaseForCandidates(array $slugCandidates, int $languageId): array
        $context = GeneralUtility::makeInstance(Context::class);
        $searchLiveRecordsOnly = $context->getPropertyFromAspect('workspace', 'isLive');
        $queryBuilder = GeneralUtility::makeInstance(ConnectionPool::class)
            ->add(GeneralUtility::makeInstance(FrontendWorkspaceRestriction::class, null, null, $searchLiveRecordsOnly));
        //restrict query to sites in rootline
        $uids = $this->getRecursivePageUIDs($this->site->getRootPageId());
        $statement = $queryBuilder
            ->select('uid', 'l10n_parent', 'pid', 'slug')
                    $queryBuilder->createNamedParameter($languageId, \PDO::PARAM_INT)
            // Exact match will be first, that's important
            ->orderBy('slug', 'desc')
