I have a fairly large project that uses Spring and Hibernate (JPA annotations). I am running on a Mac (Leopard), Core 2 Duo processor, and 4GB of RAM (1GB devoted solely to IDEA).
Performance in IDEA is almost unusable. Error highlighting and inspections are extremely slow (which greatly hurts productivity). I have to sit around for about 10 seconds waiting for IDEA to prompt me to import a class every time that I type a new class name. I regularly have to sit and wait on the editor to respond. I regularly don't see code problems until I go to compile because IDEA took so long to process the file that I didn't notice the errors.
I've submitted several JIRA issues with attached CPU snapshots, but this is ridiculous given the amount of resources available to IDEA. Are you guys testing with real-world size spring/hibernate projects?
I've heard that there will be performance improvements in the next 7.0.3 EAP. I sure hope so. Any idea when that will be released? I'm anxiously waiting...
