Date: Mon, 17 Jun 2002 16:14:54 -0400 From: Leon Bottou To: kde-devel@kde.org John Ryland and I did some extra-work on objprelink. Overview, explanations, details and benchmarks can be found in: http://objprelink.sourceforge.net/objprelink.html Summary of the conclusions: - - Recent binutils have been improved and now offer performance similar to the old version of objprelink. In fact, the new binutils and the old objprelink are two different ways to achieve the same complexity reduction. - - A new version, objprelink2, gives a new runtime link speedup. But it no longer translate into improved KDE responsiveness because the runtime linker delay is now a small component of the application startup time. I do not suggest using objprelink2 unless your linux box lacks the improved binutils. See to check. Be warned that objprelink is not a production tool. This is more a research tool whose ideas, hopefully, might be useful to others. I also suggest removing the --enable-objprelink from the KDE configure. Those who need objprelink will use objprelink2 and will not need this option. - - Leon Bottou >> Visit http://mail.kde.org/mailman/listinfo/kde-devel#unsub to unsubscr= ibe >> << - ------------------------------------------------------- - --=20 Yannick Koehler =20 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE9DkhkfuKOJNEyL1URAke7AKCY8B3k6ifsO7nCXZK6ni/f4ih/LQCfUnGm mH4FQLrh0zqh344uaXWOToo=3D =3DjnkU -----END PGP SIGNATURE-----
