Hi,
I noticed that KDE is now linked with DT_GNU_HASH optimizations.
[EMAIL PROTECTED]:~$ readelf -a /usr/bin/kmail| grep HASH
[ 3] .hash HASH 08048148 000148 00028c 04 A 5
0 4
[ 4] .gnu.hash GNU_HASH 080483d4 0003d4 0001d8 04 A 5
0 4
0x00000004 (HASH) 0x8048148
0x6ffffef5 (GNU_HASH) 0x80483d4
But I also noticed that many other applications (non-KDE) aren't linked with
this option.
Are any of you using prelink currently ?
Yes.
If yes, what have your experiences been overall (in the past and now in
present) with prelinking libraries ?
When I first read about prelinking and kde (5 or more years ago), I
thought that it would significantly help with desktop GNU/Linux becoming
more widely used. After all, who wants a long wait every time that they
want to run a particular program?
I am running Debian Unstable (with KDE 3.5.6) at present on a 1998 era
machine (PII-266, 256 MiB RAM, Cirrus Logic graphics card), so the
machine is more likely to be CPU-bound than many machines.
At present prelinking kde programs seem to take longer than non-kde
programs, presumably due to their being coded in C++ and having a large
number of shared components, but the effort does appear to be worthwhile
if programs become CPU-bound on start-up.
I haven't noticed any particular difference between prelinking now and
in the past.
