Thanks for pointing this out. Here are the new results: Bash 4.0, with bash malloc: * eval `dircolors`: 0.138s * source /etc/bash_completion: 0.735s Bash 4.0, without bash malloc: * eval `dircolors`: 0.135s (slightly slower than with debugging on, I checked several times to be sure. This is very surprising...) * source /etc/bash_completion: 0.702s Without bash malloc, the results are close to the results with debugging on. The results with bash malloc are far better now, but still slightly behind those with libc malloc, on my computer. In addition, in builtins/evalstring.c, line 271, an itrace call is not enclosed between #if defined (DEBUG) and #endif, as it should be. With my computer at normal speed (with the 'ondemand' governor), starting a new shell (and running my .bashrc) now takes around 0.4s, while it took 0.6s with Bash 3.2. This is enough to feel a difference! Nicolas
