Test of Redmine issues/issue pages with ruby patched by `compact hash` patch.
I choose this pages cause Issue model have 23 fields and User model hash 17 fields.

Ubuntu 11.04 32bit, rvm, AthlonX2 @2000GHz

    export RUBY_GC_MALLOC_LIMIT=60000000
    export RUBY_HEAP_MIN_SLOTS=1000000
    export RUBY_FREE_MIN=500000
