Yunkai Zhang commented on TS-1006:
----------------------------------
Hi guys, I have developed a patchset to solve this issue. By using this
patchset, the total memory used by TS have been controlled and will not harm
the performance at most time.
> memory management, cut down memory waste ?
> ------------------------------------------
>
> Key: TS-1006
> URL: https://issues.apache.org/jira/browse/TS-1006
> Project: Traffic Server
> Issue Type: Improvement
> Components: Core
> Affects Versions: 3.1.1
> Reporter: Zhao Yongming
> Assignee: Bin Chen
> Fix For: 3.3.2
>
> Attachments: memusage.ods, memusage.ods
>
>
> when we review the memory usage in the production, there is something
> abnormal, ie, looks like TS take much memory than index data + common system
> waste, and here is some memory dump result by set
> "proxy.config.dump_mem_info_frequency"
> 1, the one on a not so busy forwarding system:
> physics memory: 32G
> RAM cache: 22G
> DISK: 6140 GB
> average_object_size 64000
> {code}
> allocated | in-use | type size | free list name
