Very slow performance while profiling [message #495625]

Hi,

I've have downloaded a new copy of Eclipse v3.4 and run my application using the TPTP profiling. The application starts without any problems but after a few seconds it grinds to a hault running so slowely that it almost stops completely.

I have tried increasing the VM args, to:

-Xms512m -Xmx1024m

However this has no effect.

I have tried pausing the logging but this does not work either. I have also tried restricting what packages are profiled within the filter set, but again this has no effect.

Any suggestions?

Thanks

Hi,

Try modifiy the profile filter to better scope the data collection. Try
something like:
mypackage* * INCLUDE
* * EXCLUDE
The filter set above will only collect profiling data of execution in your
package(replace mypackage with your own package prefix) and exclude
everything else. This will lower the amount of data collection from other
unrelated package/component.

Hi, thanks for your reply.

However as I have stated in my original post, I have already tried restricting which packages are profiled but this does not help.

Any other suggestions?

Thanks.

You can also try 'profile to a file' where an option is available under the
'Destination' tab. Enabling the option and specifying a local file will
allow profile data be routed to a local file and using the
File>Import>Profiling File wizard to import the data in portion or range to
limit the amount of data be shown and loaded for analysis.
