So, what’s new in the CLR 2.0 GC?

Certainly that’s one of the most frequently asked questions I get (at the PDC too!). So since PDC already happened I can tell the rest of you about the new stuff happened in GC in CLR 2.0. The slides can be downloaded here. And I will be referring to some of the slides. I must…

GC talk at the 2005 PDC

I will be giving a GC talk at the PDC this September. This talk is to give you a close up view of the CLR GC so I hope to see all you hard core .NET developers there! I will talk about some internal details of generations, allocations, different flavors of GC and fragmentation (what…

Using GC Efficiently – Part 4

In this article I’ll talk about things you want to look for when you look at the managed heap in your applications to determine if you have a healthy heap. I’ll touch on some topics related to large heaps and the implications you want to be aware of when you have an application that maintains…

Using GC Efficiently – Part 3

In this article I’ll talk about pinning and weak references – stuff related to GC handles.   (I was planning on talking about finalization in this part of the “Using GC Efficiently” series but since I already covered it in pretty much detail in one of my previous blog entries I won’t repeat it here….

Tools that help diagnose managed memory related issues

I was writing an internal wiki page on performance and thought this info is useful to many external readers as well so here it goes. vadump is a good start. It’s an mstools tool – meaning you can find it on your NT CD under bin\mstools. You can take a snapshot of the process and…

Clearing up some confusion over finalization and other areas in GC

In the WinDev conference that I just went to, there seems to be some confusion over finalization (such as why it even exists and etc) and other areas. I hope the following will clear up that confusion. If not, let me know.   Finalization   1)      Why we have finalization   Finalization is necessary because…

Using GC Efficiently – Part 2

In this article I’ll talk about different flavors of GC, the design goals behind each of them and how they work differently from each other so you can make a good decision of which flavor of GC you should choose for your applications.   Existing GC flavors in the runtime today   We have the…

WinDev in Boston

I am going to WinDev this year to give 2 performance talks. Check out: http://butrain.bu.edu/windev/track2.asp (it’s from Oct 25 to 29) Below is the description: C5 – CLR PerformanceWrite faster managed code! Learn about performance engineering, tools and issues specific to managed code including: garbage collection (GC), managed code deployment and common managed code pitfalls. The…

Using GC Efficiently – Part 1

So the goal here is to explain the cost of things so you can make good decisions in your managed memory usage – it’s not to explain GC itself – it’s to explain how to use it. I assume most of you are more interested in using a garbage collector than implementing one yourself.  It…
