How much memory is occuppied at bootup on your system?

[ElDonAntonio]

Just curious to know, let's ignore for the moment all the boot apps and TSRs, if you open the task manager at boot up, how much memory is in use? and what OS?

I don't reboot often enough to care =)

After almost 2 days uptime:

$ free -m
total used free shared buffers cached
Mem: 1259 1249 10 0 0 990
-/+ buffers/cache: 259 1000
Swap: 776 32 744

only 10MB free?!?!?!?

Linux is really good at using all available memory for filesystem caching.

About 41MB.

Total memory: 1,342,177,280 bytes
Available bytes: 1,067,413,504
Used: 274,763,776 bytes

Xp never show the available system ram to be less than 120 MB (I have 256 MB ram)
Linux uses every ounce of ram available, no don't expect more than 10 MB to be free in LInux

Linux is really good at using all available memory for filesystem caching.

So is Windows. Windows dynamically grows and shrinks the disk cache as needed.

In fact Windows 9x/ME even do the same with the swap file. It's probably not as fast as a fixed size one but it's very user-friendly for people who know nothing about memory architecture.

I know this. But, IME back when I also had Win2K on this box, Linux seemed to make the transition from "lotsa memory for pagecache" to "lotsa memory for userland processes" smoother and with less thrashing. It's all heresy and personal perception, but to me Linux does a much better job with my memory. And with the scheduling enhandments that just went into 2.5 it'll make even better use of my CPU time once 2.6 released =)

I've been running my system for a day now, but its still pretty much in the same condition. Running XP with Apache, MySQL and FTP servers starting up normally I'm using:
211MB/1878MB
35 Processes

Now, this number is on the high end because I do run alot at startup, so you should know somethin is up if you start out higher than that^^
