Slow response after adding lighthouse php package

[bilalcontent]

I use this package to implement graphql.
However the response time is too slow as compared to rest api.
I simple query data from single collection. it tooks 2000ms+ to respond result..
I already implement pagination and only returns 10 records.
I use debugger to see performance. DB queries are optimized, they took only 7ms to execute query results.
I don't understand why it's too much time. Looking for suggestions:
