I didn't spot anything really wrong in there. host-gdb looks a bit useless since most likely your external toolchain already has a cross-debugger integrated. Other than that, it appears that: * Your configuration has a fairly large number of packages, some of them being fairly big stuff (mysql, perl, etc.) * The build time of perl is really large. Maybe there's something that could be done to improve this. Looking at perl.mk in Buildroot, I see that it uses $(MAKE1), so the build of this package is not parallelized. * The installation time of host-mysql seems quite large as well, I don't really see why, especially since the mysql host install commands copy just one file in Buildroot. Really, other than these little details, I believe you're simply affected by the size of your configuration in terms of the number of packages. > My build machine is a HP server with 8 core Intel(R) Xeon(R) CPU E5-2637 v2 > @ 3.50GHz. The OS is RHEL 6.4 64 bit. No virtual machine and no NFS. Seems a fairly decent setup. You have enough RAM, and a good storage system (ideally based on SSDs) ?
