Lab 2 (continu'd)
Good evening everyone,
This
blog is mostly a continuation of the second lab. This time i will be displaying
my result and the specs of the machine I was attempting to baseline php from.
So this blog is separated into the specs analysis part and the result of the base
lining.
Machine
Specifications
The
machine I was working on was the red machine, aka the machine with the ARM
processor. After installing hp I ran the following commands to outline its
specs. The information I gotten from it is displayed below.
First I
ran lshw which listed all the hardware on the machine. The output was enormous
with 7 CPU and 4 network card. but only one of the CPU was not disabled, the
rest of the output that was up is as follow:

Then I ran the command free to figure of the
memory usage, the output was a follow:
total used
free shared buff/cache available
Mem: 16713728 1176192
2205248 37440 13332288
15276096
Swap: 0 0 0
Finally for my final specs check I went to see the
file describing the CPU info and the operating release version, the output was
as followed respectively:
The
CPU information list had 7 identical entry of the following with the processor
number been the only distinguishing number.
processor : 0
Features : fp asimd evtstrm
CPU
implementer : 0x50
CPU
architecture: 8
CPU
variant : 0x0

Then the release version the machine is running
on:

Baselining
Results
For the baselining, I decided to test the amount of time php takes to echo a certain word a thousand times. I used the following command which I mentioned about
in my previous blog:
time php -r
'for($i = 0; $i < 1000; $i++){echo "hello";}'
This
tested how long it took for the machine to run the echo "hello" 1000
times. The result I gotten were pretty close to each other with only a small
degree of difference between runs. The results that kept on reappearing after
30 tries were the following times:
real 0.035s
user 0.030s
sys 0.000s
real 0.036s
user 0.010s
sys 0.020
real 0.035s
user 0.020s
sys 0.010s
These
times show that the php can reliably echo "hello" a thousand time
under 0.036 second in real time. And the use-mode and kernel time always add up
to 0.030s, mostly only sharing the time between the kernel and user-mode if
there is simultaneous runs of the php code.
This
is the result I have gotten from my understanding of how to do baselining.
Hopefully this is enough, if there anything wrong with it, or if you feel I
need to add more to complete this report please feel free to comment below.
Next time I will be finish blogging about my profiling lab which I am currently
working on.
