Subject: [Bug c++/14563] New: octave built under Cygwin very slow
Date: Fri, 12 Mar 2004 23:36:00 -0000 [thread overview]
Message-ID: <20040312233606.14563.paulthomas2@wanadoo.fr> (raw)
I am sorry if this report is imprecise and probably unhelpful but several
contributers to octave lists have failed to identify where the problem lies.
The problem is simply stated and is unique to builds of octave-2.1.xx under
latest version of Cygwin: interpreted octave programmes run 6-7 times slower
when compiled and linked with gcc-3.3.3 and its libraries, compared with 3.2.3.
Note that (i) This is problem is not present in Linux and (ii) is not dependent
on which continent one is in! ie. This problem is reproducible.
Beyond this, a variety of optimisation levels, architecture settings and so on
were tried, to no avail.
