Hi, all! I have an application written using sqlite. It writes into the database very intensively. And I noticed that it works nice and very fast but from time to time it just freezes for several seconds (I've registered freezes up to 8 secs). After some tracing of sqlite code I've found that all these 8 secs of freeze sqlite spends inside pwrite() call. So evidently when everything works fast all pwrites return almost immediately because kernel writes everything to the cache. And on some calls kernel have just flush all disk buffers, and with intensive disk usage this flushing can last for pretty long time. I've tried to set pragma synchronous = on (it's off by default for me), but it makes application to work 5 times slower which is not acceptable for me. I would be happy if there was some solution in between that, i.e. for example just a bit slower operation on every pwrite but without 8 seconds-peaks.
Does anybody know what solution I can apply here? Pavel _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
