Since you specified '-t' the links have to be "dereferenced" (find the file that is referred to) which results in opening the directory to see if the file exists, and what its properties are. With 50K+ files, opening the directory and finding the file will take tangible time. If there are multiple directories in the symbolic link path, then these directories need to be opened as well. Symbolic links are not free. More RAM may help if it results in keeping the directory data hot in the cache. If the links were hard links rather than symbolic links, then performance will be similar to a regular file (since it is then a regular file).
