Re: [ptp-dev] Opening remote projects very slow

[Dave Wootton <dwootton@xxxxxxxxxx>]

I seem to be having intermittent problems with opening remote projects. 
I'm running today on the IBM internal network so I would expect fast 
response.

I have installed a brand new version of Eclipse since I had installed 
multiple versions of CDT and PTP code into my previous Eclipse install and 
thought the multiple versions of code was slowing things down. I now have 
Eclipse 3.4 build id I20080617-2000 installed along with CDT 
5.0.2.200810240803,  PTP 2.1.0..200811031726 and RSE user runtime that 
looks like it's 3.0.1.v200809171600 (there's a bunch of RSE plugins with 
different levels, which I assume are all installed by my selection of RSE 
end user runtime from the choices I had in the Ganymede update site)

When I first created the remote C project, I still configured the two 
remote builder services to use my DSTORE RSE connections, and I started 
the DSTORE server on my AIX node. The first time I opened it, it opened 
within a few seconds. I restarted Eclipse and the next time it took at 
least 30 seconds, but opening another remote project was quick.

My project only has a single small C file (about 100 source lines) and 
editing that only takes a couple seconds.

My .project and .cproject files are fairly small, both less than 10kb.

I won't be able to test this again on the local network until 11/24 since 
I will be out of the office until then.

Hi Dave,

When eclipse is starting up the connection to the remote server hasn't 
been established yet. This means eclipse cannot access the .project file 
and that causes the project to be automatically closed. If you open the 
error log view you should see some entries to that effect. There is 
currently no setting to change this behavior.

Remote projects open very fast for me, but my testing server is on our 
intranet. 

Can you please try a few things to help diagnose the problem:

1) First we need to figure out if the problem only affects RDT projects, 
so try creating a non-RDT project on the remote server. Try using the 
regular New C++ Project Wizard to create a project on the remote server 
(indexing won't work but thats ok). Does this project take a long time to 
open after you restart eclipse?
2) After you open a RDT project and you have waited for a while try 
closing the project then opening it again. Does it take the same amount of 
time to reopen the project?
3) How long does it take to open a source file in the editor?

I'm thinking the problem might have to do with the fact that when a 
project is opened the first thing eclipse does is read the .project file, 
and the first thing CDT does is read the .cproject file. So these files 
may have to be transferred locally in their entirety, and that may take a 
while depending on the connection (and the .cproject file can become quite 
large).

[ptp-dev] Opening remote projects very slow



I have several remote projects defined in my workspace. Every time I start 

Eclipse, these projects are in a closed state, which I'm assuming is 
because of the overhead of opening a remote project. When I open a remote 
project, even one with only a couple source files, a Makefile and a couple 

executables, it either takes several minues or my Eclipse session is hung 
with an hourglass. If I click widgets in the Eclipse Window, I get the 
Windows XP application not responding dialog.

Is there any way to figure out what is going on? I can get the hang fairly 

easily.

Also, are there settings anywhere that would leave open projects in an 
open state rather than requiring me to re-open them each time I start 
Eclipse?
