Hi I have an existing application, which I am experimenting with replacing MySQL with sqlite. I have 2 boxes, one running MySQL, the other sqlite.
Execution times for every insert/update/delete SQLs is measured, and a warn log is printed if it takes > 250ms to perform the SQL. OS configuration: - kernel 2.6.39 - ext3, data=ordered, commit=1, barrier=1 On the MySQL box, I do not see any warn logs, so everything is going well. On the sqlite box, I see warn logs come up quite often, ranging from 350ms up to 4000ms to run simple insert/update/delete SQL. I have tried many sqlite configurations including: - WAL, synchronous=0, wal_autocheckpoint=0 which should make sqlite run the fastest! My question is how do I go about tracing the cause of these latencies? I am starting to look at tools like blktrace, is that the right path? Some guidance on how to use some low level tools would be appreciated, Regards Keith _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
