heliod web server: fast then, still fast today

Quick post – as an update to my post here, Jyri Virkki has published a comprehensive set of benchmarks, comparing heliod’s out-of-the-box performance to all the other current popular HTTP servers out there. Considering the last public comparison I could find of what was then Sun Java System Web server vs Apache was in 2007, these new results are highly interesting:

“heliod had the highest throughput at every point tested in these runs. It is slightly faster than nginx at sequential requests (one client) and then pulls away.

“heliod is also quite efficient in CPU consumption. Up to four concurrent clients it is the lightest user of CPU cycles even though it produced higher throughput than all the others. At higher concurrencies, it used slightly more CPU than nginx/lighttpd although it makes up for it with far higher throughput.

“heliod was also the only server able to saturate the gigabit connection (at over 97% utilization). Given that there is 62% idle CPU left at that point, I suspect if I had more bandwidth heliod might be able to score even higher on this machine.

“These results should not be much of a surprise… after all heliod is not new, it is the same code that has been setting benchmark records for over ten years (it just wasn’t open source back then). Fast then, still fast today.

You can read the total run of tests plus information graphs at Jyri’s blog entry: http://173.255.252.27/jyri/articles/.

 

Incidentally, I came across a blog post from someone who was also apparently on the Sun Java System Web Server group at Sun, who states:

“Since Oracle no longer offers updates to individual users, and refuses to respond to requests for information about how an individual can acquire the updates, I have elected to stop writing about the server. If the moribund Open Web Server gets branched I will happily contribute to the pool of knowledge that exists for it.”

Hmm, maybe someone should give him a heads-up about heliod…
