I also have NMBCLUSTERS set to 4096 but according to 'netstat -m', only 156k is allocated to mbufs!! I was wondering if I was interpretting it correctly. Any theories? Here's the netstat output: 36 mbufs in use: 11 mbufs allocated to data 9 mbufs allocated to packet headers 12 mbufs allocated to protocol control blocks 4 mbufs allocated to socket names and addresses 8/76 mbuf clusters in use 156 Kbytes allocated to network (13% in use) 0 requests for memory denied 0 requests for memory delayed 0 calls to protocol drain routines I'm running 2.1-stable (supped 3/16/96): Here's the top part of the kernel config: machine "i386" #cpu "I386_CPU" #cpu "I486_CPU" cpu "I586_CPU" ident POBOX maxusers 100 # <---- Could this have an effect? options "NMBCLUSTERS=4096" #Increase number mbuf clusters #options MATH_EMULATE #Support for x87 emulation options INET #InterNETworking options FFS #Berkeley Fast Filesystem options NFS #Network Filesystem options "CD9660" #ISO 9660 Filesystem options PROCFS #Process filesystem options "COMPAT_43" #Compatible with BSD 4.3 options "SCSI_DELAY=5" #Be pessimistic about Joe SCSI device options BOUNCE_BUFFERS #include support for DMA bounce buffers #options UCONSOLE #Allow users to grab the console options QUOTA options SYSVSHM options SYSVSEM options SYSVMSG later, --- ------------------------------------------------------------------------- Charles Owens Email: owensc@enc.edu "I read somewhere to learn is to Information Technology Services remember... and I've learned that Eastern Nazarene College we've all forgot..." - King's X -------------------------------------------------------------------------
