While working on some python wrapping, I've run into some problems
where the GC seems to take an unreasonable amount of time to run. The
code below is a demonstration:
import gc
#gc.disable()
data = []
for i in xrange(100000):
shortdata = []
for j in range(57):
mytuple = (j, i+1, i+2, i+3, i+4, i+5, i+6)
shortdata.append(mytuple)
data.extend(shortdata)
print len(data)
with gc disabled (the second line) the code runs in 15 seconds, with
it enabled it runs in 2:15, or ~9x slower. I expected some gc
overhead, but not an order of magnitude! Am I doing something
obviously wrong in the above code?
Thanks,
...Eric
