    Paging of program code

    Thank you for your reply. I know that program text is treated as computational, but my question was: does it get paged out? It can't get dirty because it's read-only. So it only has to be reread, if performance is of no concern. ciman

    Paging of program code

    Hi, do program code pages (Esid=1) ever get paged out to paging space? It may be a performance issue if the disks for paging space are much faster than the persistent location of the executable. Thanx ciman

    Process swapping issue

    Did you already try to limit the size of tmpfs in your /etc/fstab? Does "vmstat 1" show any swap activity? Is the output of "ps aux" similar to top?

    Keeping users in sync on different boxes (passwd)

    As I said offline, I meant that the changes do not have to be made synchronously on all boxes. Using a repository like cvs will let you keep track of the changes. The idea is to make the changes on one box and check them into the repository. You can then use cron to run the check-out command on...

    restrict access to performance tools

    Thank you for your suggestions and comments. There is probably no easy way to solve the problem. Scanning process tables is also nearly impossible because locally started software can carry any name and locally compiled software usually varies in size. The only hint I can get is which shared...

    restrict access to performance tools

    Thank you for your response Khalid. I've also thought about putting tools like topas in a directory not accessable to normal users or changing the file permissions. But this does not really help because the users can easily copy the needed files from another system. What I'm looking for is a...

    How to measure amount of data passed?

    You can always use iptrace or tcpdump and set a filter on the source and destination host.

    restrict access to performance tools

    Hi, we encounter problems because many users open tools to analyse performance during times of high system loads and setting lower ulimits is not an option. Changing the file permissions on tools like topas does not really help because they could be copied and started locally. My idea is to...
