Various Load Tests
Please use with care as we do not want to put extreme load to the web server.
- We have 100 documents named LoadTest_001 .. LoadTest_099.
- Each document has 20 chapters
- each chapter has 40 text lines of 72 characters
So, a document is around 60 kBytes, the whole text volume is around 6 MBytes
Each document makes 21 template calls (one per chapter and one at the end).
As this is a shared server results will not be the same all the time.
Test A
We extract 3 chapters from every document; This takes around 10 seconds typically but I have also observed response times below 5 seconds. The html output is 900 kBytes, so you need a fast connection, otherwise you will measure the time to get the result over the wire instead of the time to generate it.
Execute: DPL:Load Test A
Test B
We just pick up the template calls. This result is around 200 kBytes. Note that we process 2100 template invocations. Response time is usually in the same order as above, maybe a little faster. You may observe that the second executiuon of the test is considerably faster than the first one. Probably this has to do with MySQL caching strategies.
Note: actually we restricted the test to ~50% of the load described above. Due to some configuration limits of this webserver it may happen otherwise that the operating system throws the process out.
Execute: DPL:Load Test B
Test C
We just produce the list of LoadTest articles without steppping into them for analysis. This is fast (2-3 seconds) although we use a LIKE expression. This may change if you have more documents in your wiki.
Execute: DPL:Load Test C
Test D
We select the same articles based on the fact that they all use the same template. This requires some database join. There is no big difference to the test above.
Execute: DPL:Load Test D
