slow talend

[Anonymous]

Hello,
I am using Talend BIg data.But i am facing problem now.Talend has become very slow now. I dont know why it has become like that.
Previously it was very fast.
I am trying to load 10000 rows but it taking 400seconds for that.
Could you please tell me what is the problem behind this???

Hi,
Is it slow just for your specific job or the whole studio performance is worse than before?

Hello,
The studio performance is worse than before.
If I load the job it is coming as GC overhead limit exceeded.

hi all,
you haven't got enought memory  to do the Job.
GC overhead is about the fact that JVM spent to many time to his garbage collector.
It's due to too many java object created for the RAM available.
Increase memory or (better way) refactoring your job to optimize data management.

Hi all,
I have checked these blogs. For windows 8.1 64 bit operating system oracle java 7 is supported.so, I have installes java 1.7.1_71 version.
But If I try to check the version and incresing memory in command prompt it is coming as java version 1.8 is required. I do not know whether 1.8 is compatible for Talend big data??
What should I do now??Can you please tell me??
