Ruby on Rails

Thanks for your replay

However as sorcery is a gem and the update of last_activity_at and last login_at is made from inside the gem I cannot add the explain command. Here is some relevant log outputs

[1m [36mSQL (75.3ms) [0m   [1mUPDATE `users` SET `last_login_at` = '2015-09-25 11:22:12' WHERE `users`.`id` = 1 [0m
[1m [35mSQL (40.0ms) [0m  UPDATE `users` SET `last_activity_at` = '2015-09-25 11:22:12' WHERE `users`.`id` = 1

to be compared with

1m [35m (0.3ms) [0m  UPDATE `users` SET `visits` = 1124, `updated_at` = '2015-09-25 11:22:12' WHERE `users`.`id` = 1

where I do about the same thing in my application

Hello Hans!

In order for anyone to help you (who might not be experienced with sorcery), a lot more information is needed. But perhaps just some debugging hints would be helpful:

Could you write the output from the SQL (and a explain analyze of this query) that is triggered with the update. Are there any callbacks (or database-level triggers, index updates) doing stuff in an update, or is it only the sql that takes time?

An update to a table of 6000 rows should not take close to that time to just update a date. But there might be other stuff happening when you do this.

I am now refactoring and optimizing my code and noticed that the calls to update last_activity_at varies between 50 and 100 ms.

 I think is is too much to be ok för a simple update.

Have others different or the same experience of sorcery ?

My user table has 6000 rows and 36 fields. (too many - should be refactored anyhow). 

Can the slow response times depend on this table, sorcery, the server or the rest of application

What is wrong ?
