The analysis page is not all that efficient and can take a long time to execute, especially with 60K fields.
Having that many fields is almost always a cause to revisit your design and cut the number of fields down. Solr can cope (well, except for the analysis page and some other edge cases), but having that many fields is usually an anti-pattern.
