Yes, I'd expect more memory to improve your performance. > Anyway, my question is this: if I add memory to my system, will I > have to change the amount of swap space that I have (I currently have 64 megs > of swap space) No. If you got by before, you'll still get by. OTOH, having a more responsive system might tempt you to start more processes at the same time, which will use up more virtual memory. In this case, you may find that you need to add more swap. > and if so, will I have to re-install FreeBSD to do this? That depends very much on your configuration. You'll obviously need to find another area of disk to put your swap on (you *can* use a file, but I'd strongly recommend not to do so). If you have the choice, put it on a different disk from the first swap area. If you don't have any additional space, you'll at least have to resize a file system, which involves writing it to tape, removing it, recreating it smaller, and restoring from tape. If the file system is /usr, you'll have to do this in single user mode. If it's /, you'll have to reinstall the system. Greg
