<DIV><FONT face=Arial size=2><SPAN class=841104512-02092002>Dear GCC
people,</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=841104512-02092002></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=841104512-02092002>Allow me the humble
question to ask you if it would possible to employ a simple yet efficient
testing method from real life as opposed to the SPEC* (artificial)
test?</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=841104512-02092002>Specifically I was
thinking of running a few encoding/decoding/manipulation runs with mplayer on
sample multimedia streams.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=841104512-02092002></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=841104512-02092002>Main reasons I
could think of are:</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=841104512-02092002>- Easy to test: all
you need (sources, sample files) is available free at <A
href="http://www.mplayerhq.hu">www.mplayerhq.hu</A> (for Linux(intel,
alpha), Solaris, Irix, etc.)</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=841104512-02092002>- Important for
masses: it is one of the most widely used free software in the area gaining
probably the most momentum nowadays (amongst performace hungry
software)</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=841104512-02092002>- There is a lot of
space for improvements: even the 2.95 series perform better than the ongoing 3.x
series, but if going for the long term Intel's compiler currently wins hands
down</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=841104512-02092002></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=841104512-02092002>I know it is not a
very scientific measurement, still it does apply to a lot of people, andd is a
reason why a lot of people still stick to the older
versions.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=841104512-02092002>New features are
really an important thing to have, still they should not make it instead of the
good performance, but exploiting it.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><SPAN class=841104512-02092002><FONT face=Arial size=2>Summarizing the
above:</FONT></SPAN></DIV>
<DIV><SPAN class=841104512-02092002><FONT face=Arial size=2>- Do you think such
measurements are feasible/worth and can supply usable input for the
development?</FONT></SPAN></DIV>
<DIV><SPAN class=841104512-02092002><FONT face=Arial size=2>- Do you lack the
interest, the resources, or what else?</FONT></SPAN></DIV>
<DIV><SPAN class=841104512-02092002><FONT face=Arial size=2>- Ifyou are not
interested, is there a reasoning behind that? (point me to RTFM if
applicable)</FONT></SPAN></DIV>
<DIV><SPAN class=841104512-02092002><FONT face=Arial size=2>- In case of
positive answers do you think profiling, code analysis or what else could be the
way to improve the current situation? (get 3.x to the perf. level of
2.95.x)</FONT></SPAN></DIV>
