 +====== Buffered Log Reader ======
 +
 +The Buffered Log Reader was introduced in ProM version 4.0. It addresses the performance problems encounterd while using the classic log reader implementations on large, real-life data sets.
 +
 +It makes use of the [[ProM:​NikeFS|NikeFS]] virtual file system for optimized data access on a low layer, which allows it to provide near-operating system level speed.
 +
 +===== Features and improvements =====
 +
 +  * **Optimized for sequential read access** to ordered event log data
 +  * Achieves reading speed improvements of **up to 500 x faster** than the previous implementation on large process instances in particular
 +  * Provides efficient methods for **random access** to ordered event log data
 +  * Provides modification,​ i.e. **write access** to ordered event log data
 +  * Introduces a new, **more efficient and standards-compliant interface** for working with ordered event log data
 +  * Transparent **proxy implementation** of the legacy //classic// log reader interface
