Hi!
Sorry for my timeout...
I can't start kldstat:
root at bsd# kldload hwpmc
root at bsd# pmcstat -S k8-bu-cpu-clk-unhalted -O /tmp/logfile
pmcstat: ERROR: Initialization of the pmc(3) library failed: No such file or directory
What is wrong?
What I did:
- changed mount uptions to async,noatime.
- added to /etc/sysctl.conf
vfs.vmiodirenable=1
kern.maxfiles=65536
net.inet.icmp.icmplim=300
kern.ipc.maxsockbuf=2097152
kern.ipc.somaxconn=8192
kern.ipc.maxsockets=16424
net.inet.tcp.rfc1323=1
net.inet.tcp.delayed_ack=0
net.inet.tcp.sendspace=65535
net.inet.tcp.recvspace=65535
net.inet.udp.recvspace=65535
net.inet.udp.maxdgram=57344
net.local.stream.recvspace=65535
net.local.stream.sendspace=65535
vm.exec_map_entries=128
- recompiling mysql with
./configure --prefix=/usr/local/ --without-libedit --without-readline --without-debug --without-bench --enable-thread-safe-client --enable-assembler --with-mysqld-ldflags=-all-static --with-client-ldflags=-all-static --with-extra-charsets=complex --with-named-thread-libs='-lpthread -D_THREAD_SAFE'
Throughput improved by 5 times from 30 to 160, but server still have idle cycles. And throughput about 65-70% of Solaris.
