Python client is slow: takes 20min to query data that takes 6 seconds using a cURL command

I am finding the python client to be very very slow

I’m querying the data using python as follows, which takes about 20min to execute

result = query_api.query_data_frame('from(bucket: "testing")'
  			'|> range(start: 2020-02-19T23:30:00Z, stop: now())'
  			'|> filter(fn: (r) => r._measurement == "awair-api")'
               , org=credentials.org)

I run the same command using a shell script which extracts the data in about 6 seconds

curl https://us-west-2-1.aws.cloud2.influxdata.com/api/v2/query?org=org@org.com -XPOST -sS \
  -H 'Authorization: Token tokencode==' \
  -H 'Accept: application/csv' \
  -H 'Content-type: application/vnd.flux' \
  -d 'from(bucket:"testing") |> range(start: 2020-02-19T23:30:00Z, stop: now()) |> filter(fn: (r) => r._measurement == "awair-api")' >> test.csv
