**Describe the situation**

**How to reproduce**
On aws `c5ad.24xlarge` run a query:

```
SET max_memory_usage = '100G', max_threads = 1000, max_insert_threads = 96

INSERT INTO wikistat WITH
    parseDateTimeBestEffort(extract(toLowCardinality(_path), 'pageviews-([\\d\\-]+)\\.gz$')) AS time,
    splitByChar(' ', line) AS values,
    splitByChar('.', values[1]) AS projects
SELECT
    time,
    projects[1] AS project,
    projects[2] AS subproject,
    values[2] AS path,
    CAST(values[3], 'UInt64') AS hits
FROM s3('https://....s3.eu-central-1.amazonaws.com/wikistat/original/*.gz', '...', '...', LineAsString, auto)
WHERE length(values) >= 3
```

Performance is not bad (22 million rows are inserted per second) but can be better.
datetime = 0;
            else
                datetime = date_lut.makeDateTime(year, month, day, hour, minute, second);

            return ReturnType(true);
        }
        else
            
            return readIntTextImpl<time_t, ReturnType, ReadIntTextCheckOverflow::CHECK_OVERFLOW>(datetime, buf);
    }
    else
        return readDateTimeTextFallback<ReturnType>(datetime, buf, date_lut);

    if (!buf.eof() && *buf.position() == '.')
    {
        ++buf.position();
        
        for (size_t i = 0; i < scale; ++i)
        {
            if (!buf.eof() && isNumericASCII(*buf.position()))
