Hi,
I have been running Tor 0.0.9.2 in client and server mode for a day
now and am seeing constantly high CPU usage. If I use "top" to see the
stats, here is what I get about the 2 tor processes:
PID: 32477
USER: tor
PR: 16
NI: 0
VIRT: 37880
RES: 22m
SHR: 15m
S: R
%CPU: 82.5
%MEM: 2.3
TIME+: 368.58.30
COMMAND: tor
and
PID: 32481
USER: tor
PR: 16
NI: 0
VIRT: 17788
RES: 3100
SHR: 15m
S: S
%CPU: 0.7
%MEM: 0.3
TIME+: 4.34.33
COMMAND: tor
The first of these processes is the concern. The %CPU is consistently
high. Is this a cause of worry?
If this can be of any help to identify the problem, my /proc/cpuinfo is:
processor : 0
vendor_id : AuthenticAMD
cpu family : 15
model : 12
model name : AMD Athlon(tm) 64 Processor 3000+
stepping : 0
cpu MHz : 2002.652
cache size : 512 KB
fpu : yes
fpu_exception : yes
cpuid level : 1
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov
pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext lm 3dnowext 3dnow
bogomips : 3923.96
TLB size : 1088 4K pages
clflush size : 64
cache_alignment : 64
address sizes : 40 bits physical, 48 bits virtual
power management: ts fid vid ttp
I am using tor compiled from the source. gcc version is 3.4.2 20041017
(Red Hat 3.4.2-6.fc3)
Any ideas?
