Memory Perfection

vertigo262 · 01-11-2012, 08:22 PM

I have some servers with more then 4 gigs of ram.
And i noticed, untangle only utilizes 4 gigs of ram from them.

I also noticed, I've never seen untangle utilize that much memory.
but I'd feel somehow special if even though my servers don't need more memory, they were utilizing what they have.

If there going to be a point where untangle utilizes all of the available hardware memory?

In 9.1 it allows 70% for the java heap.
It rarely even comes close to using that on machine with 2 or more gigs.
Usually the processes and kernel tasks take less than 500 megs.

Whatever isn't used is used for disk cache for the database anyway, but we count that as free at the top of the rack, otherwise we end up with constant posts saying "OMG UNTANGLE IS MEMORY PIG IM RUNNING OUT OF MEMORY."

if you run vmstat or free -m you can see a more realistic picture of whats being done with your memory.

I know but I feel all weird that my server has 8 gigs of physical memory, yet untangle says it has only 4 gigs or memory.

like somethings not being utilized, and it should. even though it won't make a bit of difference.

ahahahah

think I'm being too nit picky?

dmorris · 01-11-2012, 09:11 PM

what is the output of "free -m" ?

vertigo262 · 01-11-2012, 09:21 PM

total used free shared buffers cached
Mem: 3546 3289 257 0 205 1916
-/+ buffers/cache: 1167 2379

You wouldn't happen to be running 32bit Untangle (x86)?
To use more than 4GB of ram, you need the x64 version.

vertigo262 · 01-11-2012, 09:46 PM

ahhh, yes, the 32 bit. is an older server and 64bit croaks.
how high does the 64bit go to?

Well Debian can go to 64 TB (Yes TB not GB) so something you dont need to worry about. I am not sure how high Untangle goes, but higher than you need.

that works for me. I will use newer hardware with 64bit on my newer systems
