I'm having difficulty understanding the three values reported in /proc/sys/net/ipv4/tcp_mem. All the documentation I've read seems to imply that it is the amount of memory used/reserved for TCP socket buffers, measured in units of pages. But assuming a page size of 4096 bytes, the numbers reported on my machine appear to be grossly in excess of the total memory in my system: # cat /proc/sys/net/ipv4/tcp_mem 196608 262144 393216 This would mean a maximum upper bound of 393216*4096 = 1610612736 bytes, or 1.6GB. But my machine has just 512MB of total memory, so there is obviously something amiss. I'd appreciate any help in understanding these variables.
