Hi all, I am putting more RAM in my machine and probably need to increase the swap size as a result. Is that a valid assumption - that I need to increase the size of the swap partition/slice if I put in more RAM? I am going from 256MB to 768MB. The size of the swap partition is currently 128MB. Thanks for all the help! -ronc

No, it is not required. If fact with 768mb of ram I would say that 128mb of swap is probably enough if it was enough with 256mb of ram. If you are adding ram because swap was being used extensivly then you might want to consider it. Regards Mark

I should think you just need less. It used to be a rule of thumb to calculate the amount of swap from the amount of RAM. In fact you jast need as much swap as the memory maximum used minus the amount of RAM you have.

If 126MB was adequate at 256MB, it is even more so at 768MB. I have
half that (384MB) and rarely use swap. I had some processes run away
and push some 30MB into swap a month ago and it just sat there until I
rebooted, probably initialization code of long running daemons. My
computer has been up for 10 days and no swap used. I do development,
compiling 20K line programs, one VMware session running for a couple
of days plus two Web servers, compiled and installed a couple of new
packages, still no swap usage.
HTH,
Jeffrey

No. You've got more ram so assuming a similar mix of programs you should use less swap.

I wouldn't worry about it unless what you are using the machine for is changing. Nick

In the old days when RAM in a computer was the exception <grin> there was a rule of thump to have the double amount of swap compared to RAM. This is crap these days. I run 384 MB, my uptime is: brauki@marvin:/home/brauki > uptime 9:37pm up 88 days, 22:53, 6 users, load average: 0.17, 0.10, 0.02 brauki@marvin:/home/brauki > Top tells me: 9:38pm up 88 days, 22:53, 6 users, load average: 0.22, 0.11, 0.03 93 processes: 92 sleeping, 1 running, 0 zombie, 0 stopped CPU states: 2.3% user, 3.6% system, 0.0% nice, 94.0% idle Mem: 392804K av, 387024K used, 5780K free, 0K shrd, 231228K buff Swap: 263048K av, 2084K used, 260964K free 48884K cached The amount of swap needed hasn't increased in month. Ruke of thumb these days is: get as much memory as you can sensibly afford and *DON'T* set swap to zero, how much you ever purchase. I wouldn't increase swap in your case. If you realy do need it ("top" "xosview" showing that you run much shorter than me ;-)) think again.
