Are you comparing Pr's render time to AE's RAM Preview time? Try rendering to video file from AE using the render queue and a codec similar to what's being used in Pr, either for the preview files or the exported video. If the render queue times in AE approach the render times in Pr, you'll know what's going on. And the dynamic link pipeline will always slow the process down a bit compared to a straight render out of AE or Pr.

Irrespective of whether you resolved your current issue, you may probably want to check this PPro with AE dynamic links slow to render discussion - it should help you understand when it's wise to rely on Dynamic Link, and when - on a digital intermediate. Pay special attention to Todd's comments.
Yeah, I'm counting both of them when rendering a H.264 file with the same settings.
I'm ready to sacrifice about 20 or 50% of rendering time using dynamic links, since it's quite common to have to adjust something inside a composition. 1500% - that's a bit too much! But the time remapping thing solved it. If that's the only stance where rendering time is so compromised, then that's ok, since speed remapping is always better done inside AE anyway. I just hope nothing else elevates rendering time that much again.
That's an excellent thread. I hadn't found that one yet. Really helpful. Thanks!

In my tests, I was actually getting slightly faster exports out of PP using DL than directly out of AE. There may be conditions when the DI is faster, but not 'always'.
Here's what Todd Kopriva said in another thread: http://forums.adobe.com/message/3813422#3813422
"When the headless version of After Effects is called upon to render frames to serve Premiere Pro for a dynamically linked composition, it's just a single process---not the multiple processes that can run when when you're using After Effects as the primary application. Other resources (e.g.,CPU threads, RAM space, hard disk bandwidth, memory bandwidth) also must be shared with Premiere Pro in the Dynamic Link scenario."
So I guess that's the whole answer. In any AE composition that's resource-heavy in terms of CPU, rendering through Premiere is way slower - especially on an i7, which has 8 logical cores. That means you're using a computer that's 8 times slower and it makes a lot of sense to pre-render in AE before, as troublesome as that might be when you have 20 or 30 AE comps in your PPro project.
The "speed" glitch I had helped a lot, but didn't really solve it.
There's a way around that. Not sure it affects anything quality-wise. You just open AE and do a full RAM preview of the sequence. Then go to PPro and "render effects in work area" for that specific part of the project. If you go ahead and do alter the original composition you're gonna now it because the preview in PPro will be gone. A bit troublesome, but better than manually duplicating and pre-rendering 30 comps and having side comps with the actual effects as backup.
Man, apparently the time remapping thing had nothing to do with it. Probably just a lucky coincidence at some point. It's taking forever to render again.
I guess dynamic link just wasn't made to be used with heavy comps... which is unfortunate, because that's usually when you need it the most. At least in my case.
Edit: Apparently Adobe Media Enconder does make use of full AE rendering capabilities. I just hadn't used AME in a long time because there was no point for my kind of work (I just exported directly from PPro), but now it makes a whole lot of sense. All's good after all.
