今天有个朋友说他的服务器运行TOMCAT+JDK环境能负载到动态1W的并发，据我的经验，如果服务器硬件配置好，负载到1W的链接应该没有问题，但这个并发有点怀疑。先不管对不对，贴上他的配置，以后有机会在测试。

是否有错误配置，自己仔细检查！！

java 环境配置：

export JAVA_OPTS="-server -Xms15g -Xmx15g -Xss128k -XX:ParallelGCThreads=20 -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:SurvivorRat
io=8 -XX:TargetSurvivorRatio=90 -XX:MaxTenuringThreshold=31"

sysctl.conf的配置：

net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_max_tw_buckets = 180000
net.ipv4.tcp_sack = 1
net.ipv4.tcp_window_scaling = 1
net.ipv4.tcp_rmem = 4096 87380 4194304
net.ipv4.tcp_wmem = 4096 16384 4194304

net.ipv4.tcp_max_syn_backlog = 65536
net.core.netdev_max_backlog = 32768
net.core.somaxconn = 327680

net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216

net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_syn_retries = 2
net.ipv4.tcp_fin_timeout = 30

net.ipv4.tcp_tw_recycle = 1
#net.ipv4.tcp_tw_len = 1
net.ipv4.ip_local_port_range = 1024 650000
net.ipv4.tcp_keepalive_time = 5

net.ipv4.tcp_keepalive_probes=2
net.ipv4.tcp_keepalive_intvl=2

net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recyle = 1
net.ipv4.tcp_max_syn_backlog=8192
net.ipv4.tcp_no_metrics_save = 0

net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_max_orphans = 3276800

fs.file-max = 9553600

net.ipv4.netfilter.ip_conntrack_max = 655360
net.ipv4.netfilter.ip_conntrack_tcp_timeout_established = 60

net.ipv4.tcp_max_tw_buckets = 60000
net.ipv4.conf.lo.arp_ignore = 1
net.ipv4.conf.lo.arp_announce = 2
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2

tomcat的SERVER.XML配置：

server.conf 配置       <Connector port="8188" protocol="HTTP/1.1"
               maxThreads="30000"
               minSpareThreads="512"
               maxSpareThreads="2048"
               enableLookups="false"
               redirectPort="8443" acceptCount="35000"
               debug="0"
               connectionTimeout="40000"
               disableUploadTimeout="true"
                URIEncoding="UTF-8" />
