I'm using mars 4.5.1. and I'm having serious problem with debugging mode.
It's just taking enourmous time to reach first breakpoint.
I'm working with large input streams files around 600-1000mb (using buffered reader), whole post processing and reading together takes around 2 minutes, but when I select breakpoint after this section, it takes enourmous time.
I've waited for 45min without any results, so I've stopped it.
Any suggestion, why debug is so slow in this case ?
Thanks for any advice !

I have a similar problem. If there are structures to inspect it can take more than 10 minutes to show the contents and can take more than one minute to execute an step. So if you need to step 10 times you'll spend 10 minutes.
I've tested with eclipse indigo, luna and mars. All of them the same. Always in ubuntu9.x, 10.x, 11.x, 14.x
Will it be fixed any year?

I've never seen that kind of behavior after using the debugger for more
than 10 years. A prerequisite for fixing a problem is typically being
able to reproduce the problem in the first place, so if no one ever
provides a way to reproduce the problem and the developers have no
theory that they might be able to use to reproduce it themselves, it's
highly unlikely that anything will be done (because it's impossible).
I.e., the title itself qualifies the problem with "in some cases", but
it doesn't illustrate the cases in a way that allows another developer
to reproduce it.

Not enough information to consider, but couple of general points
1) Debugging turns off the JIT so no speed ups by doing just in time compiling
2) Sometimes a limited data set can still product the same result (bug hit). might try using only part of the data.
3) find ways to optimize that section of code before debugging. it will be faster in debug and faster in actual use.
4) if data set gets buffered into structures in storage, are you running on large enough environment to avoid lots of swapping.
5) if using remote jvm connection for debug. try and move the eclipse and debug environment onto same machine to avoid costly network delays.
