Jason, here is a story about how much your work impacts us. We run a decently sized company that processes hundreds of millions of images/videos per day. When we first started about 5 years ago, we spent countless hours debugging issues related to memory fragmentation.

One fine day, we discovered Jemalloc and put it in our service, which was causing a lot of memory fragmentation. We did not think that those 2 lines of changes in Dockerfile were going to fix all of our woes, but we were pleasantly surprised. Every single issue went away.

Today, our multi-million dollar revenue company is using your memory allocator on every single service and on every single Dockerfile.

Thank you! From the bottom of our hearts!

indeed! most image processing golang services suggest/use jemalloc

    Yep, imgproxy seems to use libvips, that recommends jemalloc. I was checking and this is a funny (not) bug report:

    Those three all use libvips as the image processing engine, fwiw, so it's maybe not a very wide survey.

    libvips is fairly highly threaded and does a lot of alloc/free, so it's challenging for most heap implementations.

      We use libvips as well sir. We can't overstate how much we benefit from your work!

I really don't mean to be snarky, but honest question: Did you donate? Nothing says thank you like some $$$...

    It was a meta project and development ceased. For a regular project that expectation is fine, but here it does not apply IMHO.

    We regularly donate to project via open collective. We frankly did not see here due to FB involvement I think.
