This document discusses optimizing the performance of a SuiteCommerce website. It provides a case study of optimizing the Allcon Group website. Various optimizations were made including compressing images, improving API call times, and minifying JavaScript. These optimizations reduced the end-to-end journey time on the site from 30.2 seconds to 16.1 seconds, a 47% improvement. The document also provides general resources for website performance optimization.

Cautionary Note: Forward Looking Statement
This presentation contains “forward-looking” statements that involve risks and uncertainties and
assumptions. These statements are based on information available to NetSuite management at the time of
this presentation.
Actual results could differ materially from our current expectations as a result of many factors, including,
but not limited to, risks associated with quarterly fluctuations in our business and results of operations;
current macro-economic conditions and the possibility they could deteriorate; changes in business plans of
our SuiteCloud partners and other strategic partners; and the effects of competition. These and other risks
and uncertainties associated with our business are described in our most recently filed annual report on
Form 10-K for the year ending 12/31/15 and any subsequently filed reports on Form 10-K, 10-Q or 8-K.
These filings are available on the SEC’s website at www.sec.gov and on NetSuite’s website at
www.netsuite.com.
We assume no obligation and do not intend to update any forward looking statements. Customers who
purchase our services should make sure the decisions are based on features that are currently available.
Please be advised that any unreleased services or features from NetSuite that are not currently available
may not be delivered on time, or at all.
