I agree with most of the sentiments in this thread. After 1.5.8 zed density seems to have decreased but the zed spawn rate seems to have increased. At least in my experience. Just yesterday, I was reconnecting due to the FPS issue while two of my buddies were looting a small industrial area. They eventually grabbed some agro and started to pop off some zeds, eventually they spent all their ammo trying to fight their way out of the area because the zeds would spawn right on top of them. This wasn't even a big area. Although the spawn rate can be revisited the zed density was GREAT the way it was before. Moving through a village was intense! My play style (when solo, which is often) has always been the sneaky sneaky type, I would use my weapons as a last resort when it comes to zeds.
