Charset Converter seems to have a big performance regression problem since hopper-b11. I ran some regression test progran in ja locale and in C locale on Solaris. Testing in ja locale is so slow compared with testing in C locale. However, there might be a regression not only in ja locale but also in C locale. 4691440 was filed for a timeout in C locale.

(Example1)
  4691440: test/sun/io/Converter/EuroConverter.java, output of `time`
  C locale with hopper-b12
    real 0m3.21s
    user 0m1.58s
    sys 0m0.18s

  C locale with hopper-b10
    real 0m1.22s
    user 0m1.01s
    sys 0m0.11s

  ja locale with hopper-b12
    real 0m47.74s <---------
    user 0m45.78s <---------
    sys 0m1.65s <---------

  ja locale with hopper-b10
    real 0m3.13s
    user 0m1.12s
    sys 0m0.26s

(Example2)
  4690287: test/sun/io/Converter/TestConv.java
    This test took 2 minutes in C locale, 30 minutes in ja locale to pass with hopper-b12.

I added a test program which reproduces the regresesion and a profile.

Examples which were added on 2002-05-24 were recorded on Solaris. I add another example which shows how it is slow on Itanium regardless of
locales.

(Example3)
  4691440: test/sun/io/Converter/EuroConverter.java, output of `time`
  en_US locale with hopper-b13
    real 21m34.311s <---------
    user 20m33.955s <---------
    sys 0m5.836s <---------

  en_US locale with hopper-b10
    real 0m11.648s
    user 0m3.813s
    sys 0m0.243s

  ja locale with hopper-b13
    real 22m13.922s <---------
    user 20m21.591s <---------
    sys 0m7.811s <---------

  ja locale with hopper-b10
    real 0m11.901s
    user 0m3.860s
    sys 0m0.227s

Regression test sun/io/Converter/EuroConverter.java fails with Hopper build 12 on Itanium RedHat 7.2 Linux, host north-star. This test failed with an increased timeout factor of 4 x that of the original timeout value for this test.
