[hunchentoot-devel] how much virtual memory do your servers use?

[Jeff Cunningham]

I just noticed that two hunchentoot servers I'm running (on different 
machines) are using 528m and 894m, respectively, as reported by top. Yet 
the core images that SBCL creates are only 71.5m and 62.0m, 
respectively. I was wondering if there is a memory leak, so I killed 
them and restarted them. The virtual memory usage was exactly the same 
right when they started up.

I know next to nothing about garbage collection in Lisp, so if it has 
something to do with that, I'm lost. But I'm wondering if there's 
something wrong? For the core to expand to roughly 10x in virtual memory 
seems excessive and ultimately limiting in terms of server usage.

What kind of virtual memory usage do you folks see in your servers? And 
how does it correlate with Lisp implementations? If you will send me 
some numbers I will pull together some statistics and post them.

FWIW: I'm running SBCL 1.0.12, Hunchentoot 0.14.7, and the package 
dependencies all brought up to date as of when 0.14.7 was released.

Thanks,
