Sorry Joe, I don't think your reasoning is compelling. I'm sure you know how to stick "NO_PROFILE=true" in your /etc/src.conf. How far do you want to take this? By this reasoning we should set all the knobs to "NO" to speed up the build. I mean we're all competent code builders running FreeBSD-current and know how to enable knobs in /etc/src.conf. Is speeding up the build import important to you then the default base system being an comfortable featureful development environment?

We want to *encourage* the use of profiling in development. Not make it harder. With out the profiled libs being readily available, it becomes yet another step to go thru and an impediment to quick performance checking. -- -- David (obrien@FreeBSD.org) P.S. Max, would you please turn off HTML mail when sending to FreeBSD mailing lists? Many of us use that as an indication of SPAM on these lists. I've missed your responses to me due to that.
