Testing and Benchmarking (Joel)

  1. 1. Testing computer performance Introduction Introduction testing performance Going to run programmes which will push the PC to the limits and see if it keeps stable, which will determine whether it needs upgrading or not. • CPU tests • Memory usage • HDD storage I will be running these tests to see if the computer is running up to standard and see if it needs upgrading or not. I expect the PC to be up to date and run fine from the spec. I will receive the data from programmes which performs a graph that shows how much of the certain components use though high end tests. I will then use the data to determine whether the computer is fine or other things need replacing. If there’s any problems e.g. low HDD space, not enough memory, then I will also look up prices on whether it would benefit buying separate components or buying a new pc. Processor and memory usage Going to use windows performance monitoring to see what CPU and memory usage is going to be used while running certain programmes and applications. See results below.
  2. 2. Workstation Identification: TFT 1-200 Test Reason Expected Result Actual Result Comments Windows Performance monitoring of – To check the system performs normally. Average Processor Use < 50% 14% Average Memory Use < 30% 21% This is a lot lower than I predicted but is working well with its limits. Processor usage spike < 60% 53% Memory usage increase by < 20% 18% Processor usage spike – 60% 56% Memory usage increase to < 40% 19% Processor usage spike < 50% 47% Memory usage increase by < 30% 20% Processor usage spike x 2 - Launching Browser < 80% - Playing Video < 50% (Spiking throughout video) 54% Memory usage increase to 40% 28% • • % Processor Use % Committed Bytes 10 Minutes sampling every 2 seconds. Open and browse Facebook. (Firefox) Open Photoshop, including an image. Open Word, including 3 documents Launch a video from YouTube (3-4 Minutes) How much time is used when carrying out calculations – How heavily loaded the system is Long enough to give general idea of performance, sample rate short enough to catch brief spikes Used Frequently. Commonly used and heavy resource usage Generally used. Check performance when accessing Internet/Network 36%
  3. 3. Close all applications Check that memory and processor usage fall back to original readings Processor usage drop to idle Memory usage < 20% 17% As expected the CPU average was not far off correct but under estimated the memory which as dealt with the running of programmes well also running how it should be.
  4. 4. 70.0 Opened and browsed 60.0 50.0 40.0 30.0 20.0 10.0 0.0 Opened youtube video Cpu Usage Opened up photos Openend word and three documents
  5. 5. I recorded my data on a line graph so it made it more readable and better presented. Disk space usage file usage before after operating system 16294.6 16087.1 program files 11152.8 10639.8 0 0 sysvol info 9755.3 10007.1 paging file 6103.5 6103.5 recycle bin 11.9 11.9 528.1 528.1 43846.2 43377.5 user documents and profiles other Total used
  6. 6. operating system program files user documents and profiles sysvol info paging file recycle bin other This is a graph of the computer as you can see the only big difference was the program files being changed. Task B Disk Space Usage Common causes Impact of low disk space can cause, slowness, freezing, crashing.
  7. 7. Clean up methods – Windows hard disk clean up, uninstall programs from add or remove, organize data and delete unused files. Saved 468.7 hard spaces from doing clean up it wasn’t a lot down to the computer being pretty new and modern. The most space taken from the hard drive from the pie chart I created was the operating system which taken just under half of the disk space. Task c upgrading This is a price and spec of an upgrade of the pc I use in itec etc max memory, CPU and Windows to compare the option of if it needs upgrading or whether its fine as it is. Ram Cpu Hard drive Operating system Graphics card Motherboard Case Power supply Socket of processer – 1155 Memory - RAM is 6GB DDR3 – maximum 16GB Operating System supported - 32 bit would only see 4GB 6gb ddr3 Ram Intel Pentium G640 2.80GHZ 465GB with OS, 500GB on its own Windows 7 professional On board Gigabyte Technology H61M-S2PV Zoo storm 250W
  8. 8. 64 bit to see full 16GB Highest Processor Intel Xeon E3-1290 V2 @ 3.70GHz9,942$885.00* Processor now Intel Pentium G640 @ 2.80GHz2,502$69.99* Replacement of system CPU £299 Windows 7 pro 64 bit £108 RAM 16GB £117 Gigabyte GA-h81m-Ds2 socket £40 Time 3hours £90 Total £654 Upgrading price CPU £299
  9. 9. Windows 7 pro 64 bit £108 RAM 16GB DDR3 £117 Time 3 Hours £90 Total £614 Advantage The Advantage of upgrading the system is that it’s only a little bit more expensive than the upgrading price which you’re guaranteed all new parts and also have the PC for longer. Disadvantage The disadvantage is that you could buy new parts and whilst fitting you could damage equipment or could already be faulty. With upgrading you know that the parts you have already work so that you can ensure it would be the new equipment if there was a problem. Opinion My personal opinion I would go with the upgrade just because you know old parts work and if there was a problem you could tell it was new parts.
