Introduction

• A code audit is a summary of a website's database
  and code to determine possible bugs, bottlenecks
  etc.. The consequence of an audit is a report
  outlining areas that have to be improved and a
  roadmap explaining how to implement necessary
  changes.

Why Do You Need an Audit Magento website
Development?

• A Magento website audit can help if your shopping
  site is suffering from any of the following
• High maintenance costs
• Slow loading times for your site
• Difficulty to upgrade latest version of Magento
• Regular system crashes and errors

What are we looking for?

Core File Overrides

• When developing a Magento extension that attempts
  to modify core behavior it's best practice to
  utilise event observers. Unfortunately, this is
  not always possible and so it may be necessary to
  utilize an override. This is a possibly debatable
  practice as it might lead to incompatibilities
  between different extensions that are attempting
  to override the same code.
• When a Magento developer is made to use an
  override, it is also important to ensure that
  only necessary code is overridden very often a
  programmer will copy the whole core file into a
  local codepool file when they only have to change
  a single line. This may lead to issues when
  attempting to update the Magento installation, as
  the override will still be in place and some
  other repairs (e.g. bugs, security fixes etc.)
  will probably be ignored.
•  
• We will prepare a report regarding the center
  file overrides currently in place inside the your
  codebase, identify conflicts between installed
  extensions, and make suggestions regarding how
  any debatable overrides can be altered to prevent
  possible problems and keep the codebase
  maintainable.

Core File Modifications

• Another method that some Programmers Fall back
  on is to alter the center codepool files to
  inject their desired changes. This is not a
  suitable solution, as when the time comes to
  upgrade the Magento codebase to another version,
  the core file alterations will be uninstalled and
  automatic behavior is going to be lost
  potentially leading to a time-consuming
  evaluation.
• We'll identify any core Modifications currently
  within the codebase, identify the programmer's
  the reason For these alterations, and propose a
  better alternative.

7
Coding Standards

• We will use automated and manual investigation
  to evaluate the current status of the local and
  community codepools. These evaluations will
  identify areas for improvement with respect to
  adhering to Magento coding standards and we will
  propose changes that may be made to make the
  codebase compliant.

Templates

• Magento's templating system is Block-based,
  which means that the code within templates must
  be stored as light as Possible with the majority
  of business logic being siphoned into Block
  classes. The advantages of this are
• Easier for non- backend-developers to focus on
  presentation
• Reduced code duplication in multi-store systems
• Less chance of unnecessary legacy code remaining
  in code-base
• Better caching for faster page load times

9
Profiling

• Profiling is a technique used to identify
  inefficiencies within an application by
  monitoring each function call and recording the
  duration of each individual's implementation.
  This permits you to locate bottlenecks in the
  application (e.g. slow database queries) and
  determine how to fix them.
• Using the information gathered from these tests
  we'll identify areas that we believe are
  contributing to the slow page-speeds being
  experienced with clients. Additionally, we will
  recommend solutions to the issues and add an
  estimate for each.

3rd Party Extensions

• Our programmers will look at the respective
  modules which were installed on your Magento
  shop. We'll make sure that the modules are
  following best practices and are not affecting
  the performance of your site negatively.

11
Case Study

• Our client was undergoing extremely slow load
  times in their live website occasionally around
  12 seconds per petition. Almost immediately we
  could determine that the problem lay with a
  popular extension's anti-piracy alternative. In
  an effort to stop unauthorized Magento stores
  from using their extension they were implementing
  a request to their servers for affirmation.
  Unfortunately, their host has been experiencing
  it's own performance problems and preventing our
  client's website from loading quickly.
• Having identified the issue, we were able to
  indicate an alternative 3rd party extension
  offering the very same features but without the
  ideal practice offenses. Our client instantly saw
  their page speed times reduce from 12 seconds to
  2 seconds per request.

12
Conclusion

• After we have performed the audit, we'll supply
  you with a report detailing the numerous issues
  existing in your site. For each issue we will
  also include an estimate of the time that we
  think it will take to execute a solution. By
  obeying the improvements we believe will yield
  the best results, we will present you with a
  roadmap outlining the next actions you should
  take if you decide to proceed.
