¿Por qué Finder se ralentiza y empieza a fallar después de un uso intensivo?

Estoy experimentando el siguiente problema en Finder en OS X Yosemite 10.10.5.

Después de trabajar mucho con él durante algún tiempo, normalmente unos 10-15 minutos, navegando en directorios, moviendo/copiando renombrando archivos, empieza a volverse cada vez más lento, y la rueda giratoria empieza a aparecer, haciendo que todo el proceso de trabajar con él sea demasiado lento.

Estoy trabajando en un MacBook Pro 2009, con SSD de Crucial, 8 GB de RAM. He restablecido los permisos, comprobado las estructuras de archivos en el disco, probado el SSD para posibles problemas con utilidades de disco / software de diagnóstico, borrado las preferencias del Finder. El problema comenzó hace poco y no tenía este tipo de problemas en el pasado.

Si reinicio el ordenador, Finder vuelve a funcionar bien, hasta que vuelvo a trabajar intensamente con él.

Tengo los registros de giros del Finder disponibles si alguien quiere echarles un vistazo.
