＠ [Trac]TracLightning2.2

TracLightning2.2をリリースしました。今回のバージョンの最大のうりは速度向上です。2.1では、

$ ab -n 100 -c 10 http://localhost/trac/SampleProject

...

Requests per second: 2.56 [#/sec] (mean)

Time per request: 3912.500 [ms] (mean)

Time per request: 391.250 [ms] (mean, across all concurrent requests)

Transfer rate: 35.58 [Kbytes/sec] received

でしたが、2.2では

$ ab -n 100 -c 10 http://localhost/trac/SampleProject

...

Requests per second: 5.37 [#/sec] (mean)

Time per request: 1860.938 [ms] (mean)

Time per request: 186.094 [ms] (mean, across all concurrent requests)

Transfer rate: 66.33 [Kbytes/sec] received

とスループットが倍になっています。以前のミーティングでTracLightningが遅いという苦情がありましたが、これで一昔前のPCで運用しても実用的な速度が出るようになったと思います。TracLightningの最新版の2.2.2では、trac-ja 0.11.4、CollabNet Subversion 1.6.1、Maven2.0.10とミドルウェアのバージョンアップと、プラグインを一部最新化とバグfixをしています。詳細は、こちら。

TracLightningのレスポンスが遅くてストレスが溜まる方は是非最新バージョンをお試しください。
