today i am testing my service(something like cdn).system is centos
6.5,memory=32GB,bandwidth=10Gb and 4000 live stream.one mechine is 16-core
cpu and the other is 8-core cpu.the testing result makes me feel
upset,16-core cpu mechine run about 1000% cpu and play is not smooth,but
the 8-core
thanks for response.
i am using the version is go1.7, i do not know it's detail version.
yes, i have profiled my program,the cpu profile,16-core cpu and 8-core cpu
both done.the percent of the same functions almost at the same,but the
total cpu.this is interesting.
i will follow your
thanks.
i have checked my code and analyze the cpu prof file for many times.i do
not see any problems.

o yea,thanks.it's a good way to improve the performance of my program.but

thanks.yes,i thought this before too,but string is basic type of golang,to
read and write the same variable of string should not case panic i think.

the code is like this(i make it simple,but the logic is not change)
const (
Ignore = "-"
End= "\r\n"
)
type AccessLog struct {
Hash string
LowerIP string
FlowType int8
SendTime
