Bug ID: 30942
Summary: [display html] Improve the performance
Product: binutils
Version: 2.41
Status: NEW
Severity: enhancement
Priority: P2
Component: gprofng
Assignee: vladimir.mezentsev at oracle dot com
Reporter: ruud.vanderpas at oracle dot com
Target Milestone: ---
In Bugzilla 30989, John Doe reports the following:
"recording a sample program that uses lots of shared object files (most loaded
with dlopen) using "gprofng collect app" is quite fast; doing the "gprofng
display html" afterwards was... unexpected.
The first process took several minutes and wrote hundreds of MBs (mostly
disassembly) to disk
/tmp/install/bin/gp-display-text -limit 1000000 -viewmode machine -compare off
-script display.2.html/gp-script /tmp/binutils-2.41/build/test.2.er
The second process ran even much longer (actually I've killt it after taking a
single complete core for over 2 hours)
perl /tmp/install/bin/gp-display-html --whoami=gprofng display html test.2.er
Both processes ran on a single core, so the main question here is: is it
possible to use multiple cores for those tasks?"
