Description

« Hide

While editing several spring bean configuration files, the CPU was maxed out. I was still able to edit, but it was definitely slower.

My project has 23 modules. The module I was working on at the time has 50 different spring configuration files 7 spring file sets and 300+ java classes.

I've attached a performance snapshot.

Please try to install the latest bugfix EAP from here: http://www.jetbrains.net/confluence/display/IDEADEV/Selena+EAP

The latest bugfix EAP doesn't seem to help. I'm not sure that it's specific to spring bean configuration, but perhaps to parsing and validation in general. I've attached a performance snapshot from doing Code -> Generate ... -> Getter and Setter, which also pegged the CPU briefly while showing the drop down as well as the subsequent parsing and validation after the methods were inserted into my class.

Is spring config editing still slow? If so, please attach cpu snapshot for #7549.
"Generate" actions performance is an other issue

Unfortunately, I still see heavy CPU usage when editing spring files...generally when it's trying to reparse/validate the file to check for errors. I've attached a new performance snapshot.

I also opened IDEA-16352 for the generate code issue...

Attaching another performance snapshot when parsing a 2300+ line spring bean xml file.
