Salesforce mutual authentication is taking more time

Hi Team,

We had observed an issue where we are executing a SOQL with salesforce mutual authentication account. And observed that in order to process 199 records this query is taking around 10 mins. But the same query with same number of 199 records if we use a basic authentication then its taking only 1 min and 50 secs.

Could you please explain is there any performance issue when mutual authentication account is used.
