Re: Is Squid slowing down?

To answer my own question: No

Last week I did a quick comparison of the speed of Squid.NOVM.9 and
Squid.NOVM.20, which seemed to show the old squid was faster, but
as Alex Rousskov (and others) pointed out:

So I did some longer term measurements, using medians instead of average
access time, and there was no appreciable difference in speed. Here
are the results for three days with each version of Squid:

               TCP_HIT #Requests TCP_MISS #Requests
Squid.NOVM.9
               314 msecs 194,602 1391 msecs 193,178
               455 msecs 251,170 1958 msecs 194,129
               374 msecs 236,287 1648 msecs 178,613
Squid.NOVM.20
               352 msecs 174,072 1642 msecs 165,815
               382 msecs 227,845 1744 msecs 190,925
               327 msecs 224,076 1475 msecs 179,361
