ORM do thousands of such queries, especially on App start. My interest was to bench exactly: client-server-protocol on small commands, because this expose overhead of protocol.įew years ago, Xojo developer, which have port his own ORM from mySQL server to Valentina Server, have surprise us, that on such small “SELECT f1,f2 FROM T WHERE PK = x” queries VServer was few times faster of mySQL. This was the first attempt to bench and I think anyway this is the simplest scenario. But still can be interesting and important to check this of course. Although in such bench a lots of time will use SQLite engine itself, reading them from disk. For example, SELECT which finds 50-100K records and send them by protocol. Yes of course in ideal, we need yet add many other benches. Simultaneous workloads are much more interesting Same work load with 1, 2, n clients (its a server so one user is kind of low load)Ĭomplex loads (many inserters many readers etc)īenchmarking one aspect like this doesn’t say much for a server TODO: may be we will add mySQL and postgreSQL using Xojo classes. TODO: to run this against servers on local network, using Wifi (the slower the better). So everybody can check this easy if install both servers. P.S.3 This project will be in the V4RB/Examples/Advanced folder, staring from the next our beta. P.S.2 Also I can add that both servers are installed with their default settings. Valentina Server and cubeSQL both use WAL mode of SQLite engine, and shared cache mode. Valentina Sqlite Server – about 23 seconds.Results for 100K SELECTs, each SELECT finds 1 record. Valentina Sqlite Server – about 20 seconds.LOCAL SQLite – about 0.5 - 1 second on different runs.Results for 100K records INSERTS, for LOCALHOST servers (Macbook, i7, 8GB): For this we use small SQL commands, which should eat near to zero time from engine itself, so we can see overhead of server. Compare first of all client-server-protocol overhead. compare Valentina Sqlite Server vs CubeSQL server.to see overhead of Server solutions over the LOCAL sqlite engine.Loop is wrapped by transaction, providing the best speed of inserts for SQLite. It has simplest Table T1 with 2 integer fields f1 and f2. We have spend some time making simple Xojo project which do N inserts into:Ī) Valentina SQLite LOCAL db using our copy in V4RB
