I ran some benchmarks on the 3.0.1 release and the 3.1.0 release with
different options on and off. This benchmark was done with 1 client,
1 proxy, and 3 origin servers. The servers are 12 core (24
hyper-threaded) boxes and are the beefiest I could get a hold of. The
response was only a 1 byte response, so that I wouldn't make the NIC a
bottleneck.
There are a couple things to note in the benchmark results:
1. There is a huge impact in performance in 3.0.1 and 3.1.0 having
logging on and only proxying to the origin server. Turning off
logging increases the performance by 185%. I think there can be
some large performance gains to be won here.
2. There was a huge performance decrease from 3.0.1 to 3.1.0 with
just turning off the cache and only proxying to the origin. 3.1.0
is only performing at 14% of what 3.0.1 is. Turning off shared
sessions removes this decrease in performance, so some of the work
that Leif is doing might resolve this. I am going to benchmark
his patch today.
I'm wondering if we should back out the two-line "fix" from TS-880, and
instead do the proposed fix from TS-924 ?
Thoughts?
