问题 My python service uses sqlite database encrypted with sqlcipher lib. There is a performance problem when processing very first request. Database is very small and simple, requests are trivial. But processing the first request after connection takes ridiculously large time: 0.4 sec. This is a working test script. It's also quite simple (most of it are preparations and debug messages). It creates small databases (with and without encryption), populates them with some data and measures time of
