Memory Limits
Hello, I'm new to FreeBSD and really attracted to it because of the performance and stability it provides. So I am looking to develop a high performance system that may need to process over 100K UDP messages per second and be able to store information quickly. I couldn't find much documentation on the memory limits in FreeBSD, especially per-process limits in both 32-bit and 64-bit versions. Could you please point me to where I can find such information along with other performance tuning tips and characteristics of the OS to keep in mind? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Increasing per-process memory limits?
Hello, I'm currently using Zope's Plone application which relies heavily on python. When uploading large files (65 megs, possibly higher), the python process is bombing out with a 'memory exceeded' error. I'm using 4.8-STABLE . I've been told that if I increase the amount of available memory to the python process that I can resolve this issue. I've attempted increasing the max users variable in the kernel to 0, hoping it might auto-tune, but that doesn't seem to be working. Am I tweaking the wrong area? Where should I be looking? ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Try reading the manual page of /etc/login.conf: man login.conf Another way of enforcing/changing the limits that a user process has is through the 'limit' built-in command of tcsh or the /usr/bin/limits system tool.

More information about these in the tcsh(1) and limits(1) manpages. Note that the GENERIC kernel has a hard limit of 256MB, defined by MAXDSIZ (and MAXSSIZ too) in the configuration file. For modern machines with a large amount of RAM this may be inadequate. You will have to recompile the kernel to run larger processes.
