  • Improved robustness for deadlocks
    • Isolation: All read operations now default to read uncommitted to reduce problems with deadlocks.
    • Priority: Read operations will have lower priority to avoid blocking (expensive) updates.
    • Stability: Fixed bugs in error handling for deadlocks that previously resulted in crash, which resolved the deadlocks.
  • Improved scalability
    • Large cache objects now stored as files
    • Reduced memory footprint
    • Stateless operation
    • Access to full 4Gb address space
    • Fixed several memory leaks that resulted in memory fragmentation
  • Improved performance
    • Optimized streaming and conversion for data
    • Optimized string and buffer handling
    • Native integration with Redis for persistent caching
    • Native C++-level object model instead of COM+ to avoid internal overhead
  • Improved handling of data structure

    • Unified internal model
