Application Monitors may hurt performance badly

I’ve just spent two days and a night between them on the client site, trying to solve a severe performance

Just kidding. What are you lecturing about in the dev academy?

Yadid, can you identify yourself?

This is not what i said.

You wrote never use exceptions in a web application.

I not suggesting that sending and throwing exceptions is a good paractice but you can use then and its very much o.k

יש כאן בעיה מאוד רצינית של שילוב אנגלית ועברית, אז אכתוב את זה באנגלית:

You are perfectly right - the correct concept is, if you have nothing to with the exception, don't catch it, and let it bubble to the top.

However, one should understand a difference between error and exception.

I rarely accept the design that throws exceptions to indicate errors. Exceptions are exceptional to the application flow, thus the performance penalty.

Disregarding the performance issue, from my point of view, "throw new Exception(...)", is pretty similar to the GOTO statement. You don't use goto any more, so why would you throw an exception?

And believe me, exceptions seriously affect the performance of multi-user web applications. Only yesterday I've seen the remarkable 400% drop in web app performance because of thrown exceptions.

Happy coding and catching :)

ידידי להגיד שאסור ולא מומלץ להשתמש ב exception ב web applications הוא טעות מיסודה. אין ספק שיש overhead כלשהו בשימוש ב exceptions אך הוא קטן וזניח.

ככלל הכלל להשתמש ב exceptions לתפוס אותם ולטפל מאוד ולא משנה באיזו מערכת מדובר הוא מאוד פשוט:

אם יש לך מה לעשות במידע של ה execption שנתפס תתפוס אותו ( ולמשל תכתוב ללוג)

אם אין לך מה לעשות איתו תן לו להזרק במעלה ה stack.

Shay,

Yes, I do use Consolas 15, while setting up my display to the highest resolution possible.

This way, the menus are small, while the code is very readable and easy on eyes.
