Re: memory usage a la "free"

Hi Jim,

Coming from a Linux background, this threw me also. I think OBSD's
memory usage strategy is different from Linux.

My 64M machine reports the following in top:
Memory: Real: 11M/22M act/tot  Free: 37M  Swap: 2424K/515M used/tot

I'm guessing that these figures don't account for buffers/cache.

Regards,
Neil Darlow.
