Am I using too much memory? (Rails on EC2 with Resque)
- by Stpn
I am looking at the memory usage of the Rails application (it uses background processes via Resque) and since the common answer to the question, "how many workers is too many" was "test and see", I ran some memory commands and wonder if someone can help figuring if the memory usage is high enough already, or I can still add some extra workers..
so (this is all under the maximum load):
$ free -t -m
total used free shared buffers cached
Mem: 1756 1532 223 0 12 229
-/+ buffers/cache: 1291 464
Swap: 895 10 885
Total: 2652 1543 1108
$ vmstat
procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu----
r b swpd free buff cache si so bi bo in cs us sy id wa
0 0 10588 156172 13400 326476 1 6 4 0 5 4 1 0 99 0
If there is any extra info I can provide to help answer this, I would be happy to do so. If the question is strange in some way, please let me know I'd be glad to fix etc..
