Spell check has been taking an excessive amount to time to complete since adding a glossary, how do I rememdy this?

The problem lies with the use of glossaries, when spell checking UPK will scan any glossaries attached to any of your content objects. If you are spell checking topics separately and each uses a glossary, spell check will scan each glossary in it’s entirety even if they are using the same glossary. You can shave off a little time by adding the glossary terms to a custom dictionary.
