how much memory can tmpfs support?
I am using SuSE Linux Enterprise 9 on a 32bit x86 machine.
my question is can tmpfs support more than 4GB size of vmdisk? if can, what's the max memory can tmpfs suport on a 32bit x86 machine? thanks! |
i might be wrong about this cause i am vague about shmfs/tmpfs
differences if there are any in my mind this limit is for a combination of the two both are pageable and swappable unlike ramfs which might or might not be a part of this limit (some help i am) i think overall limit would be cat /proc/sys/kernel/shmall * page_size which is generally 4096 so 2097152*4096=8 GB total for all shared memory now on top of that limit i think you can specify limits on tmpfs at mount if you don't specify it defaults to half real memory. so i guess the answer is yes as long as you got that much ram+swap |
