Mautic has been extremely slow the past few days

Hi, anyone can assist?

Lately, just creating a campaign or creating a segment in Mautic, or sending a Campaign has been a painful process for me. Either the creation or saving campaigns or segment or uploading contacts is taking too long to occur or does not happen at all. Would you know the reason or remedy for this extremely slow responsiveness of the Mautic application for me? Many thanks in advance.
