Re: Re[3]: Building Win32-perl with Mingw-gcc vs. MS VC++
Hi,
an optimization level greater than 2 increased both the file size and
the memory consumption. Here are the results of my Perl 5.8.0
compilates, compiled with GCC 2.95.2:
(1) (2) (3)
----------------------------
-O1 955 392 2060
-O2 952 832 2064
-O3 1 031 192 2092
-O4 1 031 168 2088
(1)...optimization level
(2)...file size of perl58.dll [B]
(3)...memory consumption [KB] (measured while 'perl -e "sleep 20"')
Therefore, '-O2' still gives the best results.
However, Perl 5.8 generally has a higher memory consumption than Perl
5.6.1, unfortunately.
best,
rob.
