XText memory use (1000 models) [message #640042]

I'm wondering if anyone here is running XText in a project type where it validates every model file when loading the project?

If so, what is the memory utilization like when loading say a couple of hundred models or even a thousand different models (each model being a approx around on average 150 lines with around 50 possible types)?

I'm planning on using xtext in exactly this way and just thought that it might be a good idea to ask if this was a use case that was acceptable as I've been having quite a few permgen memory issues in my test workspace with just 5 or 6 models.

Thanks,

Chris

Hi Chris,

a large number of small files is usually not a problem. For Xtext 2.0 we
try to reduce the memory usage by means of a clustered builder algorithm
and a lower footprint for the parsed data.

I'm aware of projects that have 1000's of larger resources that could be
tunded to work reasonable well with Xtext 1.0, too.

Regards,
Sebastian
