read big dwg file take so long time

[brull]

when i run this program: var sw = new Stopwatch(); sw.Start(); using (DwgReader reader = new DwgReader(_file)) { doc = reader.Read(); } sw.Stop(); Console.WriteLine(sw.ElapsedMilliseconds); it takes about 80175ms to read a dwg file about 24M size.

When I use Teigha to read the same file, it takes just 2187ms. The big dwg files are usual on building design. So can you guys improve it. Thanks a lot！

This project is still actively being developed so performance is still being worked on. Since this is an open source project and you want use it, you can create a PR and assist with that performance endeavor and everyone will appreciate it. There are some areas where the parsing can improve and I'm working on ways to help with that.

Hi @brull,

Can you provide a file as an example? it would be good to detect bottlenecks and have an example.

Thanks.

This project is great！ U are great men！Cause it‘s the only one open source project written by C#. Hope it becomes better and better. Now， I am working on rising performance on my job.

I'm sorry, the dwg file designed by another guy, I have no idea can I give it to u. But I think this problem is universal. U can find a big dwg file and try it.
