XFree86 3.1 *seems* faster on Linux, but I'm sure about that. For example: logging out of my window manager and retunring to the xlogin screen takes a few seconds in FreeBSD. In Linux, I'm there in about a second. I ran a benchmark simulation (my own code, relies almost exclusively on the OS's ability to manage vast quantities of small memory blocks) under both: Linux is about twice as fast. I get slightly better disk performance out of FreeBSD, but probably not enough to be of any statistical significance. I had recompiled my Linux kernel and stripped out the unneccessary junk before giving it the boot though. My FreeBSD kernel is the same bulky one that comes in the binary distribution. That may affect performance. My problem has typically been memory constraint. Swapping performance under FreeBSD has been much better. I am quite happy now. I can run X, emacs, and still be able to run XDVI without spending 5-10 seconds waiting for the disk to keep thrashing. And until I am ready to drop $800 for 4 4Meg simms, my computer will be constrained to 8 Meg. Overall, I don't think a user will notice a difference, except for in certain very specific cases (like my simulation code). X is still pretty snappy under FreeBSD (486/66, 16 megs) and even large apps like xv 3.10 come up in no time at all. I personally prefer FreeBSD over Linux because of its BSD 4.4Lite origins, but YMMV. If you are happy with one or the other, don't bother switching unless you're a masochist like me and *like* installing OS's. :) Well, I am a bit of a masochist when it comes to that. I've now installed FreeBSD 2.0 + a patch for PPP on my system. I am *quite* happy. My system *feels* much perkier, and I have seen definite improvements in some applications emacs being the most noticeable. Plus, I'm pretty much from a BSDish background (Xenix & Sparcs) so this is like an old comfortable shoe to me. -Jon -- |jnials@io.com | Jon R.
