Hi Zeus,
Thanks for the screenshot, we are running similar tests but couldn't achieve more than 5k users.
It would help us if you could share the OS tuning parameters and cache sizes in Openfire. Though we've gone through this forum to get this info, somehow we are unable to shoot up above 5k.
This could help us verify our settings once again. Below are the existing configurations in our system.
OS Params:
cat /proc/sys/fs/file-max
>fs.file-max =102642
open files (-n)65536
# ulimit -Hn
>65536
# ulimit -Sn
>65536
Cache Size:
cache.group.size -> -1
cache.userCache.size -> -1
cache.username2roster.size -> -1
cache.vcardCache.size -> -1
