no but we are in the same problem for three months

the original issue that the cpu spikes for 100% for random time and
then goes down

AMD Phenome 2 X6 / 16 GB ram / 1 TB SSD /2 TB SATA/

i know that one core is working for squid but the spikes occurs not
only in peak times and after spike the CPU return to 30% or 20%
i can see the error because of gcc or while loops
CC=x86_64-pc-linux-gnu-gcc CFLAGS=-O2 -pipe -m64 -mtune=generic
  LDFLAGS=-Wl,-O1 -Wl,--as-needed CXXFLAGS= --cache-file=/dev/null
--srcdir=.
is this cflags true or ????
