Because these may take a long time to run, we recommend starting them before you leave at the end of your day so they can run over night.
1. Reboot your computer and press the f12 key as soon as you see the
Dell screen that shows right before the Windows screen. If you miss it,
just wait for Windows to finish starting and try again.
In this stress test up to 500 users perpetually access the phpinfo.php script from the web server without a click delay/think time (i.e. The users reload the page immediately after the last request is finished). This chart shows the 'Spectrum of Click Times' which shows the results of this Ramp Test. The three axis are: With more and more users accessing the server the request times deteriorate, the bar’s maximum is. Description: SQLQueryStress by Adam Machanic is a free tool for SQL Server programmers. It is designed to assist with performance stress testing of T-SQL queries and routines. Testlimit is a command-line utility that can be used to stress-test your PC and/or applications by simulating low resource conditions for memory, handles, processes, threads and other system objects. Usage: Testlimit -h -u -p -n -t -n KB -u -i -g object size -a -d -l -m -r -s -v MB -w -c count -e seconds. Dell screen that shows right before the Windows screen. If you miss it, just wait for Windows to finish starting and try again. Now you should see the black boot menu screen. From here it depends on which model of computer you have, but the steps are similar for all. Use the up/down arrows to select “Diagnostics” or “Utility.

3. Use the up/down arrows to select “Diagnostics” or “Utility
Partition” or something similar and press the enter key.
4. A few pre-boot tests may run and ask you some questions. Answer as
best you can (these tests aren’t important now). At the end of these tests
press any key to boot the utility partition.
5. Then the hardware diagnostics screen comes up while loading some
software, and then a menu with 4 buttons. Click on the “Custom Tests”
6. Check the Non-interactive tests only box near the top of the window
and select “All Devices” from the tree on the left.
7. Click “Run Tests” button.
8. Email or call the IT Office with any error messages you get. If you
don’t get an error message, then your issue is probably software or network
related. Network issues outside the Methodist Bldg. will have to be resolved by your Internet Service Provider (ISP).
In order to test and troubleshoot networks we need tools that allow us to generate network traffic and analyze the network's throughput performance. This is true for both wired and wireless networks. We focus strictly on 802.11 (WiFi) networks because analysis tools are relatively scarce or, when available, tend to be rather expensive and overly complex to use. Also, because WiFi networks are sensitive to RF interference from other wireless devices, they are more difficult to troubleshoot and transient changes in the local environment may affect their performance. Tools that are typically used to troubleshoot wireless networks report signal strengths of RF interference or beacons from an access point in units of dBm or RSSI (relative signal strength indication). But what do these really mean? How do these translate in terms of the performance of your wireless network?
Our wireless network adapter may report the beacon strength of our access point to be -53 dBm or -65 dBm or -73 dBm or <fill-in some number>. Or, our RF spectrum analyzer displays a -74 dBm interference peak in the middle of channel 6. Or, we and our neighbor or the business next door have our access points configured to use channel 11? Is this good? Bad? Doesn't matter? Ultimately, the bottom line and what we care about most is throughput -- that is, how many bytes-per-sec can be transferred from one node on the wireless network to another. The dBm and RSSI numbers don't mean much if you can't somehow relate them to a performance metric -- the most relevant being 'bytes / sec'. In order to properly troubleshoot a wireless network we need a way to benchmark its performance, so as modifications are made we can determine whether or not they really make a difference in the network's performance.
This is where NetStress fits in. It's a simple tool, originally created for our internal use, which we later realized would also be of value to others. Here's the ideal scenario: You install a new wireless network and it works perfectly. Run NetStress and record the benchmark results for later reference. Sometime in the future when either you or others suspect performance has declined then run NetStress again and compare the latest results with those you gathered when the network was first installed and working 'perfectly'. The results of that comparison will indicate whether or not there really is a problem and dictate which steps to take next (if any). Regardless of your technical expertise or how expensive your diagnostic tools, if you are modifying a wireless network or making decisions to modify it and you are not testing throughput then you risk wasting time and resources going down the wrong path.
