Jan 03, 2011 · Note that newer versions of glibc exist (we used the default for CentOS 5.2), and that the newest version of tcmalloc is 1.6, but we encountered undiagnosed application instability when using versions 1.5 and 1.6. Web server throughput glibc derives its allocator from ptmalloc, so their performance similarity is no surprise.
Dec 09, 2017 · The sqlite versions are the same (1.21). I'm guessing this is an ext4 vs. zfs issue. The report generator only reads the database. I also had difficulty with X on this machine (it has Intel graphics hardware and yes, I installed xf86-video-intel). Instead of using the Intel driver, it used the Vesa driver and the graphics performance was awful.
When compiling Rust on a Linux system Rust will dynamically link against glibc by default. For background, linking against glibc is not necessarily a bad thing - you can reduce your binary size and benefit from any performance or security updates without changing your code. However, when vending your project to users, linking against something ...
Nov 14, 2003 · Java vs. C benchmark - the benchmark is in Microsoft Word format FreeTTS performance case study - at Sun Research Linux Number Crunching - used 1.4.1 VM, got very different results than I did, maybe due to floating point optimizations added in 1.4.2
Future directions for this comparison include detailed performance benchmarking and inclusion of additional library implementations, especially Google's Bionic and other BSD libc ports. Bloat comparison. musl. uClibc. dietlibc. glibc. Complete .a set.
musl provides consistent quality and implementation behavior from tiny embedded systems to full-fledged servers. Designed from the ground up for static linking, musl carefully avoids pulling in large amounts of code or data that the application will not use.
Mar 27, 2017 · Note that this may add over 60 seconds of startup time. (This, itself, needs performance analysis.) See the resulting flame graph as a SVG or PNG. The workload is ttcp (test TCP), a TCP benchmark written in Java. The flame graph shows that most CPU time is spent in socketWrite(), with 9.2% in releaseFD().
Xbench was developed by Spiny Software to provide a comprehensive benchmarking solution for Mac OS X. Xbench is useful not only for comparing the relative speeds of two different Macintoshes, but also for optimizing performance on a single machine.
