Hello All.
Below are some compile times for 2.6.20 on an fx-62
running Centos64 with various 2 gig sticks of
dual channel ram (See previous posts with subject
of 'segfaults with 8gig of ram' for more details.)
It seems dual channel will compile a kernel faster,
but only gained around 30 seconds over 20 minutes.
Below are the shortest/longest compile times of
several compiles done over the weekend.
Compile consisted of make menuconfig (save .config)
time make dep clean bzImage modules
2 sticks dual channel @800mhz
10 samples
================================
real 791.46
user 664.10
sys 93.85
real 799.88
user 665.30
sys 93.87
4 sticks dual channel @400mhz
5 samples (before it hurled booting)
================================
real 876.19

3 sticks single channel @800mhz
6 samples

I am putting together a pretty high-end workstation and originally had
ordered 2gb sticks. Here's my [main] hardware specs:
Abit AB9 QaudGT motherboard
Intel Core 2 Duo E6600
Seasonic M12 PSU
3 Seagate 250gb SATA II disks
Since my main goal is to run VMWare Workstation with host OS Centos 5
(when it comes out), I was originally interested in using 8gb memory.
But after posting the following thread on the Abit motherboard forums, I
discovered that the Intel P965 Express chipset does not fully support
PC6400 (800) DDR2 memory:

So I returned that memory and went with 4 1gb sticks of low latency
(4-4-3-8) memory instead, trading memory capacity for performance.
