> Hi,
> Recently, we started to prepare a new revision of our blog-post in which we test various implementations of replicated queues. Previous version can be found here:  [https://softwaremill.com/mqperf/]
> We updated artemis binary to 2.13.0, regenerated configuration file and applied all the performance tricks you told us last time. In particular these were:
>  * the {{Xmx}} java parameter bumped to {{16G (now bumped to 48G)}}
>  * in {{broker.xml}}, the {{global-max-size}} setting changed to {{8G (this one we forgot to set, but we suspect that it is not the issue)}}
>  * {{journal-type}} set to {{MAPPED}}
>  * {{journal-datasync}}, {{journal-sync-non-transactional}} and {{journal-sync-transactional}} all set to false
> Apart from that we changed machines' type we use to r5.2xlarge ( 8 cores, 64 GIB memory, Network bandwidth Up to 10 Gbps, Storage bandwidth Up to 4,750 Mbps) and we decided to always run twice as much receivers as senders.
> From our tests it looks like version 2.13.0 is not scaling as well, with the increase of senders and receivers, as version 2.2.0 (previously tested). Basically is not scaling at all as the throughput stays almost at the same level, while previously it used to grow linearly.
> Here you can find our tests results for both versions: [https://docs.google.com/spreadsheets/d/1kr9fzSNLD8bOhMkP7K_4axBQiKel1aJtpxsBCOy9ugU/edit?usp=sharing]
> We are aware that now there is a dedicated page in documentation about performance tuning, but we are surprised that same settings as before performs much worse.
> Maybe there is an obvious property which we overlooked which should be turned on? 
> All changes between those versions together with the final configuration can be found on this merged PR: [https://github.com/softwaremill/mqperf/commit/6bfae489e11a250dc9e6ef59719782f839e8874a]

> Charts showing machines' usage in attachments. Memory consumed by artemis process didn't exceed ~ 16 GB. Bandwidht and cpu weren't also a bottlenecks. 
> p.s. I wanted to ask this question on mailing list/nabble forum first but it seems that I don't have permissions to do so even though I registered & subscribed. Is that intentional?
