4F推:我跑你的 code 沒用 psyco 時 4.47~4.53s, 有用時 2.05~2.08s08/07 04:07
5F→:而且有用 psyco 時記憶體使用量大幅減少約 121MB08/07 04:24
6F→:更正：我是跑 b(7500000), 不是 b(10000000)08/07 04:26
7F→:另外，如果把 range(x) 改為 xrange(x), 則沒用 vs. 有用：08/07 04:27
8F→:3.51~3.61s vs. 2.02~2.07s, 記憶體使用量則都很少08/07 04:30
9F推:再確認一次：你的 CPU 與 Python 各是用 32 or 64-bit?08/07 04:51
10F→:注意 "Psyco does not support the 64-bit x86 architecture,08/07 04:53
11F→:unless you have a Python compiled in 32-bit compatibility08/07 04:54
12F→:mode."08/07 04:54
15F推:Duo T5750 是 64-bit x86 的，但你說你的 Vista 是 32-bit,08/09 07:11
16F→:CPU 應該是以 32-bit 運作，那理論上 psyco 要能作用才是 @@"08/09 07:14
2F推:確認過 system requirements 還有安裝方式嗎？或是先跑跑它08/06 04:27
3F→:所附的 test 資料夾中的測試範例看看是否有加速？08/06 04:29
4F→:http://psyco.sourceforge.net/psycoguide/req.html08/06 04:32
5F→:http://psyco.sourceforge.net/psycoguide/binaries.html08/06 04:32
6F→:我的是裝在 [Python 安裝目錄]\Lib\site-packages\psyco08/06 04:35
7F→:如果以上都沒問題的話，可能有看看文件中的附錄 A 和 B:08/06 04:38
8F→:A: http://psyco.sourceforge.net/psycoguide/node25.html08/06 04:38
9F→:B: http://psyco.sourceforge.net/psycoguide/node29.html08/06 04:38
10F→:(更正錯字：倒數第三行) 要08/06 04:42
7F推:原來 list comprehension 有 (...) 這樣的寫法呀 o_O!12/16 00:43
8F→:查了後發現是 2.4 版提供的，又學到一招了 :p12/16 00:43
1F推:Python 可 run 的平台首頁就有講了：http://www.python.org/11/24 14:01
4F推:大推 :)10/29 14:15
6F推:times 不大的前提下，我覺得程式看起來清楚比較重要耶!?11/01 16:05
7F→:不然這樣寫不僅記憶體吃得多，就連執行速度也比較慢啊 @@?11/01 16:06
