Hello, I am creating a db in tmpfs with following PRAGMA settings: PRAGMA encoding = "UTF-8"; PRAGMA default_cache_size = 4000; PRAGMA synchronous = OFF; PRAGMA temp_store = MEMORY; PRAGMA journal_mode = OFF;
I am creating four tables on the run and inserting 8000 records in two of these tables ( 4000 each ) and it is taking around 21 seconds(on an average). The records contain metadata information of audio files along with file stat info. When tmpfs is not used, the time taken is almost same. Please note that all the two tables that are getting populated are indexed : Table 1 is having 1 string Index Table 2 is having 2 string index The insertion is done under BEGIN IMMEDIATE transaction.(100 records at a time) under a single thread. Pl. suggest why I am not able to get any performance gain for tmpfs? Thanks and Regards, Souvik Please do not print this email unless it is absolutely necessary.
