Searching slow on Linux

[munotshubham (Shubham Munot)]

Hi,

So I've indexed around 50k documents in a linux machine and a windows machine.
I am just firing one query using Node.js which is like

client.search({
        index: 'patientdb-test',
        type: 'db',
        body: {
            explain: "true",
            size: 100,
            query: {
                bool: {
                    must: [
                        {
                            multi_match: {
                                query: req.params.word,
                                fields: ["FirstName", "LastName", "PreferredName", "DateOfBirth", "PMRecordNumber"],
                                type: "cross_fields"
                            }
                        }
                    ],
                    filter: {
                        term: {
                            "PracticeID.keyword": req.params.pid
                        }
                    }
                }
            }
        }
    }).then(function (resp) {
        var hits = resp.hits.hits;
        res.send(hits);
    }, function (err) {
        console.trace(err.message);
    });

It is taking around 1-2 seconds on the Linux Machine.
It is taking around 20-100 milliseconds on the Windows Machine
