How to reduce SSR loading time in Next JS?

Question

I am trying to reduce the load time that SSR is taking right now, So, I am building a property page I have a next link that takes me to that property page but it takes too much time so it seems the API takes too much time so how can I reduce the page loading time?

export async function getServerSideProps(context) {
  const props = {
      properties: [],
      total: 0,
      filters: {},
      map: {
          latitude: DEFAULT_LATITUDE,
          longitude: DEFAULT_LONGITUDE,
          zoom: DEFAULT_ZOOM,
      },
      lookups: {
          basements: [],
          residentialTypes: [],
          residentialStyles: [],
          condoTypes: [],
          condoStyles: [],
          statuses: [],
      },
  }

  const filters = ProcessFiltersFromQuery(context.query)
  props.filters = { ...filters }

  const request = {
      limit: 500,
      first: true,
      orderBy: 'dom',
      orderByDir: 'desc',
      classes: ['Condo', 'Residential'],
      offer: 'Sale',
      ...filters,
  }

  const filteredCheck = { ...filters }
  delete filteredCheck.offer
  const filtered = Object.keys(filteredCheck).length > 0

  const center = context.query.center
  if (center) {
      const coords = context.query.center.split(',')
      const latitude = coords[0]
      const longitude = coords[1]

      props.map = {
          latitude: Number(latitude),
          longitude: Number(longitude),
          zoom: 15,
      }
      request.center = {
          latitude,
          longitude,
      }
  }

  props.useMap = !(filtered && !center)

  if (props.useMap && !center) {
      request.useMap = true
      request.bounds = DEFAULT_BOUNDS
  }

  const token = cookies(context).mss_token

  const properties = await IndexProperties(cleanup(request), token)
  if (properties.data) {
      props.properties = properties.data.properties
      props.total = properties.data.count
  }

  props.lookups.basements = Lookups.basements
  props.lookups.residentialTypes = Lookups.types.residential
  props.lookups.residentialStyles = Lookups.styles.residential
  props.lookups.condoTypes = Lookups.types.condo
  props.lookups.condoStyles = Lookups.styles.condo
  props.lookups.statuses = Lookups.statuses

  return { props }
}

How can I reduce that time and user don't have to wait long enough for the product loading.
