Latency   
I`m testing the Photon version of Tau.  

When I launch a build ( custom Makefile ). It takes the IDE about 10 seconds to realized the makefile is done.  That 
means 10 extra seconds before the error are parsed and display.

Anyway to get rid of this?

Re: Latency   
Well parsing of makefiles takes these extra 10 seconds. You can turn off 
parsing and it will be faster but you won't have errors in the problems 
view.

That can`t be right.  The output is about 5 lines, that`s 2 seconds per line...   

I made a small change so that a make clean doesn`t output anything at all.  Yet it still takes 10 seconds.  During this 
10 seconds in the status bar I can see "Building targets.: (0%)".  During this 10 seconds there is about 20% of the 
processor used by devb-eide and 30% by pvm.

More investigation:  The project is made up of multiple sub-directory which all have their own makefile. It seems that 
when I launch a make  in a sub-directory after it`s done build it, it ends up scanning files in the whole project.  I 
caught these with pidin fd. Maybe it`s looking for binaries ?

Re: Latency   
Yeah this is true. It is doing refresh after the build to pick up new 
binaries, maybe this takes lots of time.
You can try to run pvm with enabled jit (optimized bytecode), it would 
take a LOT time to start up but it suppose to be faster after that.
To start with jit remove option -nojit from qde.ini file

Nah still too slow.  I wanted to see if removing -nojit made some operation faster, I tried a search/File, didn't work 
at all.  Seems like it's not doing anything.

That being said the overall performance is not up to par with the Windows version so I'm not going to spend any more 
time on the self hosted version of Eclipse for now.

I have the same problem under Windows. Any way to disable the scanning of binary after the custom makefile has returned?

Re: Latency   
If there is any preference about it, they would be in 
Windows->Preferences, type Refresh in filter box.
I could not find anything related to "Refresh after build". You can ask 
on cdt newsgroup.
