Hi, dolt is a replacement for libtool which promises to fix some performance issues of libtool, many of which have since dolt’s release landed in some versions of libtool.
I have made some first measurements of dolt under Debian8 (hardly any improvement) and OS X 10.10.5 (noticeable speed-up), see https://issues.apache.org/jira/browse/MESOS-4271 While dolt should fallback to libtool if incompatibility with the build host is detected, it would be great if we could gather some more feedback on this change (e.g., does it horribly fail the build on your host, what speedup does it provide, …). Cheers, Benjamin
