Awesomium減少webview內存使用量

Question

我正在製作瀏覽器遊戲的機器人。我正在使用http://awesomium.com連接到該頁面。 我使用webview來顯示curstom表單上的頁面，但問題是，經過很長時間，awesomium_process達到200k的內存使用量，並不斷上升.. 我不知道如何減少內存使用..（我無法使用webcontrol，因爲injectmousemove不會對webcontrol中的flash內容造成影響）

任何人都可以幫我嗎？

這裏是我的代碼：

有幾件事情可以做，以改善這種情況，但它也取決於你有什麼地方努力，你的遊戲是如何構建的。

如果您使用的是awesomium 1.7.4，您可能會考慮恢復到Awesomium 1.7.3，新awesomium中的內存使用量已大幅增加。

您可以使用內存分析器來查看是否正在創建任何影響內存使用情況的內存泄漏。

當awesomium進程的大小增加時，一個原因是因爲javascript執行在頁面上創建對象，請確認您沒有在您設置的任何javascript代碼中泄漏內存。

Flash也可能泄漏內存，請確認您沒有泄漏任何內存。

Web上有很多工具可用於分析這些不同的組件。我已經使用ANTS進行了.NET的內存分析，我發現它非常有用和信息豐富。

如果您運行1.7.4，我會採取的第一步是嘗試1.7.3，因爲它可能是一個相當簡單的更改。我最近（實際上昨天是這篇文章）必須將我的代碼庫移回到1.7.3，因爲1.7.4中的內存問題我確信這些問題將得到解決，但我現在需要穩定。
