Jason, here is a story about how much your work impacts us

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!
