Measuring query throughput
Measuring the query preformance is a delicate thing with a big danger of producing biased results.
We provide here some numbers without intending to compare Strus with other systems.
The test just gives you a hint about the quantity structure you can handle with
a search index of the size of Wikipedia English with Strus on an Intel NUC.
Nothing more. The main intention is to convince people to give it a change rather than giving
a base for a business decision. For a decision you need a fair comparison.
This is not provided here.
Nevertheless this test shows more than a statement like: This engine processes bla bla gigabytes of (unspecified) data per second on hardware you can rent or buy.
We will run two small tests (each of them with only 1600 queries) on the Wikipedia demo search solution with all involved services written in Python with all the involved weighting and summarization functions used.
The system was not at all optimized for this case. Before running the test the storage servers were restarted.
You have to take into account here that the Strus Wikipedia demo system, makes a preselection on title features only if your query consists of only high frequent terms (stopwords) like for example "to be".
Test with BM25
The first test runs 1600 random generated BM25 queries, 800 of them single term, 800 of them with two query terms. The queries were built from randomly selected words starting with a capital letter from the forward index of the index dump. The two term queries are built from words appearing at least once as a sequence in the index.

The query terms have the following distribution of document frequencies:
Each test was splitted into 8 scripts, each script running 200 queries of the form:
wget --quiet -O tmp/output.P.1.htm 'http://demo.project-strus.net/query?s=BM25&q=Mexican'where 'Mexican' is the query in this example. I run these 8 scripts in parallel from my laptop. The test scripts are part of the strusWikipedia project in the subdirectory benchmarks/parallelQueries. Each test run produces 8 real time measurements from which we take the highest one as the total running time to get the number of queries executed per second.
The test with the BM25 query evaluation scheme produced the following numbers:
real 41.68 real 42.14 real 42.45 real 42.65 real 42.86 real 42.88 real 43.09 real 44.62
The longest time for a set of 200 queries was 44.62 seconds. So we get
1600 / 44.62 = 35.8 44.620 / 1600 = 27.8 E-3meaning 35 queries per second or 28 ms per query
The test with the BM25pff (with proximity) query evaluation scheme produced the following numbers:
real 128.92 real 130.53 real 130.65 real 131.89 real 132.22 real 132.23 real 132.48 real 132.60
The longest time for a set of 200 queries was 132.60 seconds. So we get
1600 / 132.60 = 12.1 132.60 / 1600 = 82.8 E-3meaning 12 queries per second or 83 ms per query. This reflects the intuitive impression, that the BM25 with proximity in Strus is about 3 times slower than the native BM25.
