Recently on the -ac tree, hdparm -t has been telling me about 29MB/s, while on the main tree even since 2.4.0 and through 2.4.4-pre4, it tells
me about 35MB/s. I do use a VIA chipset, but I don't recall it (686a) was afflicted by the hardware bug. Furthermore, I believe performance was poor even before Alan Cox merged the VIA fixes, i.e., somewhere
before 2.4.3-ac7.Forgive me if this has been already reported.

Re: performance degradation on -ac tree

Hi all,

I've been lurking for some time now, unsure of whether I had some special issues in my own setup, but seeing these others come forward has emboldened me to speak out as well.

I am running a RH 7.0 box with all updates and then some, and generally trying each new 2.4 pre patch or -ac variant, with the addition of Andrew Morton's low latency patches.

I have been noticing a marked performance degradation with recent -ac kernels compared to Linus' versions.

This is based mainly on 2 things, one precisely measurable, the other more objective, but tangible to me nonetheless.

First, the quanitifiable test:

I have noticed that with e.g. the 2.4.0-test kernels, and e.g. 2.4.2, netperf to localhost gets between 350-400 MB/s.

With recent -ac kernels, e.g. 2.4.3-ac5, netperf to localhost gets more like 250 MB/sec.

secondly, a subjective test:

When giving it the quake 3 arena test, playing against internet opponents, e.g. 2.4.2 feels very responsive, and I seem to be able to run circles around opponents, dodge and turn very quickly.

The same activity with recent -ac kernels feels like running through molasses, very sluggish, and it is I who am repeatedly outmaneuvered and embarrassed. It's quite awful.

Re: performance degradation on -ac tree

Quoted 4 lines

I have noticed that with e.g. the 2.4.0-test kernels, and e.g. 2.4.2, netperf to localhost gets between 350-400 MB/s. With recent -ac kernels, e.g. 2.4.3-ac5, netperf to localhost gets more like 250 MB/sec.

Thats one to ask Dave Miller.

Quoted 3 lines

The same activity with recent -ac kernels feels like running through molasses, very sluggish, and it is I who am repeatedly outmaneuvered and embarrassed. It's quite awful.

The 2.4.3ac VM is far from ideal at the moment. Its a lot smoother for server use and it doesnt spend so much time randomly killing wrong things but it does stall too much

Re: performance degradation on -ac tree

There is a bit more clarity on the performance degradation issue now - In fact the degradation only appears when using iptables. It's just that sometime shortly after 2.4.2, the hit imposed by iptables got worse.

For instance:

netperf results without iptables with iptables
-----------------------------------------------------------------

2.4.2                 400 MB/s                      330 MB/s
2.4.3-ac10            400 MB/s                      250 MB/s

BTW, the stock seawolf kernel gets the highest netperf results ever seen on this box, around 450 MB/sec, but with iptables or ipchains module loaded, it falls to about 270 MB/sec.

Just a data point fyi -
