Running from a desktop to a headless server, and based on side-by-side clicking, IceCat/GuixSD takes ~5x times as long as Mozilla/Debian to respond to clicks. Further, Mozilla/Debian takes ~5x times as long as Mozilla running on the desktop. The bottom line: IceCat/GuixSD is unbearably slow.
Has anyone else seen this? Is there a known IceCat/GuixSD performance problem? Details: Two identical headless servers with 3.4GHz E3 1240 V3 CPUs and PCI SATA NVMe SSDs. One runs Mozilla Firefox 45.7.0 on Debian 8.x. which was updated a few months ago. The other runs guix 0.14.0.617-e2f37 from a couple weeks ago. The desktop is XQuartz/MacOS 10.13.2/iMac. Both servers are reached via the same physical 1000BaseT network. Swapping the server switch port/cables doesn't affect the result.
