I seem to recall the GCE images have faster CPUs but spend more time booting the VM. For rdma-core I counter balanced the VM spin up time by avoiding the matrix feature. rdma-core has a very fast compile at 19s, I can run all four compiler passes in less time than it takes to spin up and configure the VM, container or not :\. For something like libfabric you might get a win if you do the same and run fabtests on one of the compiler's output instead of for both. Plus, if you use trusty you don't need to download and compile rdma-core, just install libibverbs-dev and librdmacm-dev from Ubuntu. But at the end of the day, it depend what you expect out of travis. rdma-core has travis setup to try and show that the code is clean with bleeding edge rolling release distros (eg forward looking).
