Comment 2 for bug 1529173

For integer workloads such as installing an OS you should expect TCG to be about 12x slower than KVM on average. That is on current master; note that TCG has gotten faster in the last couple of years. See a performance comparison from v2.7.0 to v2.11.0 for SPEC06 here: https://imgur.com/a/5P5zj

I've therefore marked the report as invalid, as I don't think the aforementioned speedups will change your experience dramatically.
