Description
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
allocated | in-use | type size | free list name --------------------|--------------------|------------|---------------------------------- 671088640 | 37748736 | 2097152 | memory/ioBufAllocator[14] 2248146944 | 2135949312 | 1048576 | memory/ioBufAllocator[13] 1711276032 | 1705508864 | 524288 | memory/ioBufAllocator[12] 1669332992 | 1667760128 | 262144 | memory/ioBufAllocator[11] 2214592512 | 2211840000 | 131072 | memory/ioBufAllocator[10] 2325741568 | 2323775488 | 65536 | memory/ioBufAllocator[9] 2091909120 | 2089123840 | 32768 | memory/ioBufAllocator[8] 1956642816 | 1956478976 | 16384 | memory/ioBufAllocator[7] 2094530560 | 2094071808 | 8192 | memory/ioBufAllocator[6] 356515840 | 355540992 | 4096 | memory/ioBufAllocator[5] 1048576 | 14336 | 2048 | memory/ioBufAllocator[4] 131072 | 0 | 1024 | memory/ioBufAllocator[3] 65536 | 0 | 512 | memory/ioBufAllocator[2] 32768 | 0 | 256 | memory/ioBufAllocator[1] 16384 | 0 | 128 | memory/ioBufAllocator[0] 0 | 0 | 576 | memory/ICPRequestCont_allocator 0 | 0 | 112 | memory/ICPPeerReadContAllocator 0 | 0 | 432 | memory/PeerReadDataAllocator 0 | 0 | 32 | memory/MIMEFieldSDKHandle 0 | 0 | 240 | memory/INKVConnAllocator 0 | 0 | 96 | memory/INKContAllocator 4096 | 0 | 32 | memory/apiHookAllocator 0 | 0 | 288 | memory/FetchSMAllocator 0 | 0 | 80 | memory/prefetchLockHandlerAllocator 0 | 0 | 176 | memory/PrefetchBlasterAllocator 0 | 0 | 80 | memory/prefetchUrlBlaster 0 | 0 | 96 | memory/blasterUrlList 0 | 0 | 96 | memory/prefetchUrlEntryAllocator 0 | 0 | 128 | memory/socksProxyAllocator 0 | 0 | 144 | memory/ObjectReloadCont 3258368 | 576016 | 592 | memory/httpClientSessionAllocator 825344 | 139568 | 208 | memory/httpServerSessionAllocator 22597632 | 1284848 | 9808 | memory/httpSMAllocator 0 | 0 | 32 | memory/CacheLookupHttpConfigAllocator 0 | 0 | 9856 | memory/httpUpdateSMAllocator 0 | 0 | 128 | memory/RemapPluginsAlloc 0 | 0 | 48 | memory/CongestRequestParamAllocator 0 | 0 | 128 | memory/CongestionDBContAllocator 5767168 | 704512 | 2048 | memory/hdrStrHeap 18350080 | 1153024 | 2048 | memory/hdrHeap 53248 | 2912 | 208 | memory/httpCacheAltAllocator 0 | 0 | 112 | memory/OneWayTunnelAllocator 157696 | 1232 | 1232 | memory/hostDBContAllocator 102240 | 17040 | 17040 | memory/dnsBufAllocator 323584 | 0 | 1264 | memory/dnsEntryAllocator 0 | 0 | 16 | memory/DNSRequestDataAllocator 0 | 0 | 1072 | memory/SRVAllocator 0 | 0 | 48 | memory/ClusterVConnectionCache::Entry 0 | 0 | 560 | memory/cacheContAllocator 0 | 0 | 112 | memory/inControlAllocator 0 | 0 | 112 | memory/outControlAllocator 0 | 0 | 32 | memory/byteBankAllocator 0 | 0 | 576 | memory/clusterVCAllocator 0 | 0 | 48 | memory/evacuationKey 6144 | 0 | 48 | memory/cacheRemoveCont 270336 | 262560 | 96 | memory/evacuationBlock 4997120 | 3968416 | 976 | memory/cacheVConnection 798720 | 522080 | 160 | memory/openDirEntry 0 | 0 | 64 | memory/RamCacheLRUEntry 56426496 | 56426304 | 96 | memory/RamCacheCLFUSEntry 9584640 | 6168000 | 960 | memory/netVCAllocator 0 | 0 | 128 | memory/udpReadContAllocator 0 | 0 | 128 | memory/udpWorkContinuationAllocator 0 | 0 | 160 | memory/udpPacketAllocator 0 | 0 | 304 | memory/socksAllocator 139264 | 68544 | 1088 | memory/sslNetVCAllocator 0 | 0 | 128 | memory/UDPIOEventAllocator 671744 | 115520 | 64 | memory/ioBlockAllocator 28305408 | 28301520 | 48 | memory/ioDataAllocator 2273280 | 406320 | 240 | memory/ioAllocator 1904640 | 1489920 | 80 | memory/mutexAllocator 1105920 | 188544 | 96 | memory/eventAllocator 2359296 | 129024 | 1024 | memory/ArenaBlock
this box will crash every 2days, so the memory waste may no that high
2, our production reverse system:
physics memory: 16G
RAM cache: 8G
DISK: 1516 GB
average_object_size 16384
and it run for a much long time:

our team is working on the memory free issue, trying to improve the memory management. and this a big project, the more input|comment the better.
