Need for Speed: Removing speed bumps from your Symfony projects ⚡️Łukasz Chruściel
No one wants their application to drag like a car stuck in the slow lane! Yet it’s all too common to encounter bumpy, pothole-filled solutions that slow the speed of any application. Symfony apps are not an exception.
In this talk, I will take you for a spin around the performance racetrack. We’ll explore common pitfalls - those hidden potholes on your application that can cause unexpected slowdowns. Learn how to spot these performance bumps early, and more importantly, how to navigate around them to keep your application running at top speed.
We will focus in particular on tuning your engine at the application level, making the right adjustments to ensure that your system responds like a well-oiled, high-performance race car.
Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.

A class is a data type in Java that
defines a template or blueprint for
an object. In other words a class
refers to the category or type of
objects. So your cat Kitty is of
type cat, your red Mercedes is of
type car and your bank account is
of type savings account. A class
has variables defining properties
and methods defining behaviour
of its objects.
Class

4. Spotle.ai Study Material
Spotle.ai/Learn
A variable is a named
field containing
information associated
with the class or object.
For example the colour
variable of Class Cat
indicates the colour of
the specific cat. A
variable has a data type
indicating what type of
variable (number, text,
array, custom, etc) it is.
What Are Variables?
4
Colour
= Black
Colour
= White
5. Spotle.ai Study Material
Spotle.ai/Learn
Types Of Variables
5
Local
Variables
• A variable declared inside
a class method/
constructor is called a
local variable.
• Other methods in the
class are not aware of
these variables.
• For example, consider the
drink method of class Cat:
drink()
{float milk_qty = 10}
milk_qty is a local
variable of method
drink().
Instance
Variables
• Are variables declared
inside a class but outside
of any method or
constructor.
• These are called instance
variables because their
values are instance
specific and are not
shared among instances.
Eg. the colour variable of
the Class Cat.
Class
Variables
• Are variables declared
inside a class with the
keyword static.
• A single copy of a static
variable is shared among
all instances of a class.
• Static variables are used
to declare common
properties – for example
the number of legs of a
cat or the mileage of a
brand of cars.

Instance And Static Variables
My colour is my
colour. None of
your colour!
7. Spotle.ai Study Material
Spotle.ai/Learn
Methods are used to describe
behaviour of the objects of a class.
A method is a set of statements
which is referred to by name and
can be invoked at any point in a
program. It performs a logical unit
of work.
For example get_mileage() method
in class Car is used to return a
specific car’s mileage. In our cat
example, meow() and drink_milk
are methods of the cat objects.
What Are Methods?
7
Meow()
Meow()
8. Spotle.ai Study Material
Spotle.ai/Learn
Public int getMileage()
{
return mileage;
}
Public void refuel(float fuel)
{
total_fuel = total_fuel + fuel;
}
Syntax Of A Method
8
Return type indicates
the data type of the
variable returned by a
method.
This indicates the
parameter with which
the method is invoked
from within a program.
This is the method
name.
The body of the
method describes the
functionality.
9. Spotle.ai Study Material
Spotle.ai/Learn
What Are Constructors?
9
Constructor is a block of code defined
in a class that initializes the newly
created object.
A constructor is structurally very
similar to an instance method in Java
but it is not a method as it doesn’t
have a return type.
A constructor is automatically called
when the instance of a class is
created.
Public class Cat
{
Cat()
{
System.out.println(“Meow !I
am a new Cat.”)
}
}
Definition Example
10. Spotle.ai Study Material
Spotle.ai/Learn
Types Of Constructors
10
If a class does not have
any constructor, Java
compiler inserts a default
constructor into the code.
A default constructor, for
class Cat, looks like this.
Note the body is empty:
Cat()
{
}
The default constructor is
not inserted if you
implement a constructor
for your class.
A no-argument
constructor is one that
takes no arguments or
parameters.
For example:
Cat()
{
System.out.println(“Meow
!I am a new Cat.”)
}
}
Default
Constructors
Parameterized
Constructors
No Argument
Constructors
A constructor with
arguments or parameters
is known as a
Parameterized
constructor.
For example:
Cat( String msg)
{
System.out.println(“Meow
!I am a new Cat with a
special message” + msg)
}
}
11. Spotle.ai Study Material

string breed;
static no_of_legs = 4

I am a new Cat.”)
}

{
System.out.println(“Meow on demand!”);
}
}

Spotle.ai/Learn
What Is An Object?
Think of the class like the Mercedes blue-print
and the object like your brand new Mercedes.
12
Object is an instance of a class.
An object is a self-contained
component with methods or
behaviour and properties or state.
Objects are the real world
manifestation of a class like your
house is the manifestation of the
architect’s blue-print. Or your car is a
real object of type car.
Objects occupy memory location at
run-time.
13. Spotle.ai Study Material
Spotle.ai/Learn
Creating An Object In Java
13
Cat myKitty = new Cat()
Cat myKitty is the declaration of the
object myKitty of class Cat.
Objects are created by using the
operator New which allocates memory
for the object.
The Cat() command invokes the no-arg
constructor we defined earlier (In Slide
11).
So when Cat myKitty = new Cat()
is run, the following gets printed:
Meow! I am a new Cat.
14. Spotle.ai Study Material
Spotle.ai/Learn
Class Object
A class is a data type.
It defines a template
or blueprint for an
object.
Object is an instance
of a class.
Does not occupy
memory location.
Occupies memory
location at run time.
Does not really exist
as it only provides a
template. You can
therefore not perform
operations on a class.
You perform
operations on objects.
Class Vs Object
14
Think of the class like the Mercedes blue-print
and the object like your brand new Mercedes.
