runtime/pprof: unconditional gzip compression of profiles · Issue #74022 · golang/go
The pprof format specifies that profiles must be gzip compressed on disk. Go implements this by unconditionally applying gzip (level 1) compression to all pprof profiles it produces. This is proble...

As I said on the last devlog, I'm focused on optimizing parts of the game, so my current environment is surrounded with "pprof" profilers haha 🕵️🔎🔎

I just published a proposal for a new RSS profile type for Go.
It aims to solve the issue that the heap profile typically shows < 50% of process RSS, which is very confusing.
It should also help to quickly identify when memory usage is dominated by cgo.

WebAssembly Profiling with Pprof and Wzprof - Rajiv Ranjan Singh & Naman Lakhwani
Don't miss out! Join us at our next Flagship Conference: KubeCon + CloudNativeCon Europe in London from April 1 - 4, 2025. Connect with our current graduated, incubating, and sandbox projects as the community gathers to further the education and advancement of cloud native computing. Learn more at https://kubecon.io WebAssembly Profiling with Pprof and Wzprof - Rajiv Ranjan Singh, A.P. Moller - Maersk & Naman Lakhwani, Independent Embark on a journey to supercharge your Go applications targeting WebAssembly by harnessing the profiling capabilities of pprof and wzprof. This session unravels the intricacies of optimizing Go-powered web applications for maximum performance. Discover how pprof provides deep insights into CPU and memory usage, forming the foundation of our optimization journey. Complementing pprof, wzprof, tailored for WebAssembly, offers streamlined performance analysis during module execution. Through practical demonstrations, learn how pprof and wzprof work together to resolve performance bottlenecks, optimize computations, and manage memory effectively. This talk equips both seasoned Go developers and WebAssembly newcomers with essential tools and techniques to maximize application efficiency and speed.

Uff dużo pracy dla jednej osoby , zwłaszcza jak się typescript nie lubi, ale teraz .... Ma to sens zostało mi wdrożenie pprof .. zobaczymy co z tego wyjdzie , prawie mnie pokonał crosscompile.... Najnowsze wersje github.com/SunDUINO/Sun.... Oraz na vscode marketplace ...

Go at least has some variant of this (and heapz but seemingly not fragmentationz) available if you import net/http/pprof and stand up the HTTP server for it.
A `go tool pprof $that_endpoint/debug/pprof/mutex` (and similar) will even get you a nice report.
But, yeah, that introspection is nice.

Got it figured out! Thanks all. :) Answer was:

Super happy with the improvements from last night.
Went back to normally running at 60fps ( some cases drops still).
I just fixed 2 functions that I found thanks to the 'pprof'.
I'll continue now that I'm at it 😂

I would recommend not throwing away any of the raw data, rather just filter on the visualization side.
We run a free service where you can upload your profiling data and with a URL parameter you can pre populate filtering.

Looking at total memory allocations, only 12.6% of memory allocated is being used by subscribers, the rest is just for consuming the relay firehose, dealing with the MST bits, and unmarshalling CBOR.
You can see that in both total allocated memory bytes and total objects allocated.

Great product and really nice to see such intuitive use of eBPF and pprof 💯 I used pprof just few hours ago so I really appreciate tooling around it.
I just realised that you’re also based in Berlin, no wonder the name sounded familiar to me. 🧸

100% agreed, gcx has been an absolute game changer, as is pprof/pyroscope, and many other tools
though I also have been trying to left shift finding those weird things until before prod, but we have a lot of pre-existing systems with a lot of issues that need debugging!
