问使用Android，在SQLite中将小图像作为小块存储是否有显著的性能影响？

EN

public long insertLocation(RecordLocation recloc)
{
    Long lValueToReturn;

    ContentValues kvPairs = new ContentValues();
    kvPairs.put(FieldsLocation.LATITUDE,    recloc.mLat);
    kvPairs.put(FieldsLocation.LONGITUDE,   recloc.mLon);
    kvPairs.put(FieldsLocation.DESCRIPTION, recloc.mDescription);
    kvPairs.put(FieldsLocation.IMAGE,       recloc.mImage);

    lValueToReturn = mDB.insert(TABLE_NAME_LOCATIONS, null, kvPairs);

    return lValueToReturn;
}


public class RecordLocation

    public double mLat;
    public double mLon;
