SimpleSAMLphp handles 12000 logins per minute

Posted 4 days ago by and...@uninett.no

I’ve done some performance testing with simpleSAMLphp as an IdP.

There are several factors that affect the throughput, including session size, session handler, etc.

In our test setup we used memcache as session handler and a ... [More] session size of 1k (a couple of attributes).

The server was on HTTPS, using Apache pre-forked. We used a distributed JMeter setup, with my laptop to control the attack, and 4 of my colleges office computers to perform the “attack”. There was ONLY ONE server (remember that you can loadbalance simpleSAMLphp to multiply the performance, we’ll soon extends the performance tests to include LB). The server was a blade server with 8x 2.8GHz Intel Xeon CPUs and 32GB memory.

While doing 12000 per minute (200 logins per second) the server still was able to process logins from a independent server, although sometimes the request did hang for a long time before beeing processed.

We did not use an LDAP in our test setup. Remember that your LDAP may be a bottleneck. [Less]

Markdown rocks

Posted 11 days ago by and...@uninett.no

If you’re tired of XML and verbose markup languages, the best readable (and writable) markup language I’ve seen is Markdown.

I’ve started using it as input format for drupal, and I’m considering whether it could compete with docbook when it comes to writing technical documentation. What do you think? One big feature that markdown has over docbook is that it can be parsable in realtime (on web). Doing XSLT on docbook is really taking CPU and time.

I also would like it as a input format for Dokuwiki, but could not find any stable available module.

BTW: Textile looks terrible - I don’t understand it, do you? [Less]
