STS, Maven and Java running very slowly

Question

I'm running a new install of ubuntu 12.04 afer an upgrade killed my display drivers.

I've reinstalled everything but STS is running extremely slowly - it seems to hang on every mouse click and I rarely get to the stage that I can actually use it for anything.

I think this may be linked to a maven or java issue, as when I try to run a mvn package on a simple project, it takes about 20 minutes on "Building jar" and "Building war" never seems to end (I have left it for hours).

I don't know where this performance issue could be coming from - I've tried a couple of different java versions but nothing seemed to help.

I know this question is a little vague but I need help finding what question to ask to resolve this issue!

STS version 3.2.0

java -version

java version "1.7.0_21"
Java(TM) SE Runtime Environment (build 1.7.0_21-b11)
Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)

mvn -version

Apache Maven 3.0.4
Maven home: /usr/share/maven
Java version: 1.7.0_21, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-7-oracle/jre
Default locale: en_GB, platform encoding: UTF-8
OS name: "linux", version: "3.5.0-27-generic", arch: "amd64", family: "unix"

Edit to add: Another thought - could this even be an fs mounting issue? I have all my documents on a seperate ntfs partition. I don't know if that could have this effect of making read/writes very slow? Ill try creating a project on the local disk

Answer 1

Solved! Quite a peculiar scenario but it did end up to be the disk mounting that was making everything in my document partition run extremely slowly.

Verified the theory by copying a project to the local partition and running the mvn package command which was previously hanging. It worked immediately. so I've removed the offending lines from the /etc/fstab, rebooted and manually mounted the partition, and now it runs fine.

Answer 2

you should show your configuration files. What kind of project?
I have had a similar problem. Was because i was not using connection pooling. Look at this example.
maven-jpa-hibernate-spring-too-slow
