One way to slice and dice is to proceed until things get sluggish, then export, SAVE PROJECT AS, and give it a unique # or name, so as to not overwrite earlier saves. Now delete all but the very end of what's been edited thus far, and continue with the next section in the same way. When all parts have been exported, import them, clean up the overlapped edits and export the final. As the exported sections are now single clips where all effects have been composited, this should go quickly.
One easy way to export parts of a long project is to swipe the sequence - hold the left mouse button and drag the cursor. Then right-click, and a menu will appear.
