Runtime system stdlib/kernel

• Memory handling
• Improved memory management on UNIX (using mmap)
  gives less fragmentation and better performance.
• Improved diagnostic BIF's retrieving memory
  information

5
Runtime system stdlib/kernel

• File I/O
• Improved multithreaded I/O
• Support for scatter/gather I/O in the file
  driver to improve performance.
• Improvements of the real-time characteristics for
  the single threaded case (default) when
  reading/writing very large blocks.

6
Runtime system stdlib/kernel

• New functions in ets and dets
• select/2 and select_delete/2 more powerful than
  match_object/2 and match_delete/2.
• New variants of match, match_object and select to
  retrieve matching objects in smaller chunks
• member/2 to check for a key without retrieving
  the whole object
• insert/2 accepts a list of objects to be inserted
  in one call
• delete_object, delete_all_objects, from_(d)ets,
  to_(d)ets, init_table and test_ms (only ets)

7
Runtime system stdlib/kernel

• Improved disc based storage
• Dets, improved speed and resource consumption
  ,works better with multithreaded I/O.
• Disk_log, Improved performance, especially when
  using multithreaded I/O.

8
Runtime system stdlib/kernel

• Misc improvements
• Improved inet_driver (IP)
• Named ports
• Improved floating point arithmetic

Compiler/Language

• New syntax for setting all remaining fields in a
  recordmyrecordaVal,__
• New logical operators andalso, orelse
• New more powerful inliner
• Optimizations regarding records
• Optimizations regarding list comprehensions

10
Mnesia the DMBS

• Improved performance for tables with disk_copies
  property.
• Improved performance for disk_only tables
  (because of dets).
• Mnesiaselect/2 and 3 which can replace use of
  mnemosyne and mnesiamatch_object.
• Synchronous transactions

11
Orber and Corba services

• Improved performance for inter-ORB communication,
  and reduced memory consumption.
• Completely redesigned cosEvent , now OMG
  compliant.
• New service cosFileTransfer compliant with
  preliminary OMG spec.
• New service cosProperty compliant with OMG.

12
Megaco/H.248 Media Gateway Protocol

• New application Megaco
• the first implementation of the H.248 protocol
  within Ericsson
• The Megaco application in Erlang/OTP supplies a
  framework for building gateways and controllers
  on top of the Megaco/H.248 protocol stack.
• Tested in interop event together with several
  other vendors

Asn1, compiler and runtime functions

• Support for Information Objects according to
  ITU-T X.681 for both BER and PER
• New options ber_bin and per_bin which uses
  bit-syntax and binaries in the encode/decode
  routines.Gives improved performance.
• Support for DER (a restriction to BER)

16
ODBC, interface to SQL databases

• ODBC redesigned
• Improved speed
• New functions
• Retaining old functions for backwards
  compatibility

17
Tools

• Cover a new Code Coverage tool which replaces
  Coast. Significantly improved speed and much
  easier to use.
• Fprof a new profiling tool which measure how time
  is used in Erlang programs. Uses trace to file to
  minimize performance impact, and displays time
  for calling and called functions.

18
Misc

• Webtool a framework for web based tools, Web
  interface to appmon and cover
• For a more complete list read the Highlights doc
