Yes I read that fastdebug-info a long time ago and IMHO what is says
about speed is incorrect. In Java 6 fastdebug was horribly slow as well
and things do not seem to have changed.

I downloaded and installed Java 8 from Oracle and that does run as
expected. It seemed to be slightly faster than OpenJDK 7 on some
benchmarks I did but the difference was very small.

Title:
  Openjdk-8-jdk is a debug build

Status in “openjdk-8” package in Ubuntu:
  Confirmed

Bug description:
  The current openjdk-8-jdk package  for Ubuntu 14.10 installs a version
  of java that reports "openjdk version 1.8.0_01-internal-fastdebug" as
  its version. This is a debug build that works painfully slow. Using it
  to run Eclipse and do stuff like building projects or even open source
  everything takes about five times as long as when using openjdk-7-jdk.

  This package should not contain a debug build, if at all a debug
  version should be in a separate package.

  Expected: getting a normal production build to run Java programs for
  normal use.

  Instead: II got a debug build that runs Java programs painfully slow
  (and probably with a lot of memory overhead although I did not check
  that).
