Hello.
I found it and just try to use mesh with firefox at ubuntu14.04 but it seems rss is higher than default.

monitoring rss value every second during run speedometer2.0 with cat /proc//status | grep VmRSS
https://browserbench.org/Speedometer2.0/

average rss MB with mesh : 445 MB
average rss MB without mesh : 391MB

Also i have checked _meshedPageCountHWM value but it shows 0 after finish speedometer.
I really want to see how much memory could be saved by mesh.
So please share good scenario to see memory saving by mesh if possiable.

Thank you.

@yongtaek-lee hi and thanks for the report! Can you confirm that you recompiled Firefox to not use jemalloc? Unfortunately, due to the Firefox build system we are not compatible with stock FF builds.

here is an example of disabling jemalloc in a mozbuild file:
