There isn't enough information in your message for anyone to take an
educated guess. If you see evidence of vacuum not being performed on
certain tables for a while, yes that may explain queries taking too
long, which may cause other symptoms. If analyze hasn't been performed
for a while, then you may see suboptimal plans for the queries.

But, again, you haven't provided enough information, so you may not get
very helpful answers.
