After a longer pause I finally had a moment to work on my packages in the openSUSE Build Service. I now added RPMs for the Google Performance Tools and enabled building on openSUSE 10.2. From the perftools project page:
Perf Tools is a collection of a high-performance multi-threaded
malloc() implementation, plus some pretty nifty performance analysis
tools.
I hope you will find them useful. It would be interesting to see, if a KDE desktop linked against tcmalloc() is significantly faster than using the default glibc malloc()...
