[Gems-users] very slow performance

[Fengguang Song <song@xxxxxxxxxx>]

Hi,

I've tried to build a 16 CPU system. There was no problem
when following the QuickStart document. But it is extremely
slow, an "ls" command takes about 40 minutes.
A small system with 1 CPU took a couple of seconds to run "ls".

I only loaded the ruby module. Without ruby, simics runs
pretty fast even on the 16-cpu system (for "ls").
I'm wondering if I run a one-minute program, the simulation
might take several days. Is it normal, or it is just related
to Solaris console? Is there anything I could do to make it
run faster?

As ruby reported, 208669177 instructions (for "ls" command)
took 42.6038 minutes (~81KIPS). Is the number normal?

Here is the machine I'm using:
OS: Red Hat AS4
Processor: 4x3.0Ghz Intel Core 2 Duo
Ram: 4G

Thanks much,
Fengguang
