Ext Speeder Acceleration• Convert large databases into
In-memory Objects
• Extreme Performance, real time Big Data
• Downloads a copy of the most recent database state in the background
• Seamlessly switches over to the copy
• Configurable in-memory reload time-Default reload each hour-Configurable per second, minute or hour
• Multi-versioning concurrent control (MVCC)
Automatic Data Reload
Deployment Scenarios
• Stand Alone Java SE 8
• Java EE Application Server- Oracle WebLogic
- Tomcat / TomEE
- Glassfish / Payara
- Wildfly / JBoss
- Jetty

Ext JS Versions
• No change in Ext Speeder - Works for these versions: -Ext JS 6 (BufferedStore) -Ext JS 5 (BufferedStore) -Ext JS 4 (Use regular Store with buffered = true)
Accelerating Run-Time Performance
How Ext Speeder improves your performance
• Data Database objects are stored in-memory
• Sort A sorted view of every column resides in-memory
• Filter Resolved without querying the database. In-memory filtering lookup.
• Skip In-memory dictionaries improve skip performance
• Total Number of results are cached for each set of parameters
Performance Test : Open database
• Open database with US doctors
• 40 million objects
• Comparison with and without Ext Speeder

Ext Speeder Example
• ~25 million rows
• User Interaction “scrollbar”- Sort by price
- Skip to row 15,342,132
- Show 50 following rows
Ext Speeder Example
• Use the sorted view “price” in descending order (instant)
• Use the dictionary to find the closest token for 15,342,132 (instant)- Closest token might be $30.23 at 15,342,102
• Find that token (instant)
• Skip (15,342,132 – 15,342,102 = 30 rows) (30 operations)
• Retrieve the following 50 rows directly from memory
• Convert to JSON
