ECO Files Blank Title 95521

While running a tabanalysis procedure heading up to a dump & load I noticed that I have 82 ECO groups with 150,000 ECO REvs containing 800,000 ECO Operations and 1,170,000 ECO Materials. My question is could this large number of records be a probable cause for the engineering workbench taking a long time when opening? If this is the cause how would I clean up this potential mess?
