Hi Haitao,
Are you sure it's the serialization the problem? Asking this 'cause, if
your database/model doesn't have an index over `eth_tx_hash`, it may
take a very long time for the database to find the records you need.
(Also, maybe using `.select_related()`
(https://docs.djangoproject.com/en/2.1/ref/models/querysets/#select-related)
on your query may speed things up by bringing all related elements, in
case your model have a few ForeignKeys or ManyToManyFields).

record =
ExchangeCoinTransaction.objects.filter(eth_tx_hash=eth_tx_hash)
if not record:
return False, "the eth transaction is't exchange coin transaction"
json_rec = serializers.serialize("json", record)
record = json.loads(json_rec)
#This simple query database, and serialize the results of the
operation takes 3 to 4s, similar operations may take more time
