Hi ,
I am seeing a FreeBSD 11.x OS poor performance issue .
CPU is Intel(R) Xeon(R) Gold 5115 CPU @ 2.40GHz ( dual socket CPU with 10
cores per socket )
I have attached a simple program which creates thread and computes time
taken to create this thread. On this CPU with FreeBSD 11.x OS it takes 9000
to 15000 micro seconds ( us) to create
just one thread.
On other platforms this thread creation time is usually 20 to 30 us only.
Any idea why it takes so much more time with FreeBSD 11.x ?
Is there any processor specific tuning that needs to be done ?
Thanks,
Steevan
