I'm a new Poser user, old hand at DAZ, & you probably already know this, but if you dock the Library window in Poser, it helps to speed up performance. Though on the 64 bit version, it will not allow you to dock it. Keeping an external, not in Poser itself, content/runtimes  also helps. Like I said, you probaly already know, so if you do, just ignore me. Lol!
