ASP性能 [英] ASP Performance
问题描述
我已经阅读了大量关于ASP性能的文章，而不仅仅是我可以算。我b $ b看到有冲突的信息，所以我自己做了一些测试。
getstring和getrows实际上比记录集循环更快。
但是，我已经在循环中读到了Do While ...循环是最快的并且
对于...接下来最慢但我的测试证明不是这样。
我已经测试过了：
做...循环
一边做......循环
做直到...循环
虽然... Wend
For ... Next
我没想到我除非我使用了
集合或数组，否则我可以使用For ...进行准确的测试。
我也看到有关字符串连接的冲突信息和
Response.Write
这样更好吗？
dim str
str = str& 这个
str = str& 那个
str = str& 这个和那个
Response.Write str
或者这个？
dim str
Response.Write" this"
Response.Write"
Response.Write" this and That"
我也看到了加速最后一个：
响应
。写这个
。写那个
。写这个和那个
结束
是否有可靠的性能测试可供审核？
它是否因语言而异？ ASP：VBscript，ASP：JScript，C / C ++，Delphi，
VB，C＃

I''ve read numerous articles, more than I can count, on ASP performance. I
see conflicting information so I did some tests on my own.
getstring and getrows are actually faster than recordset looping.
However, I''ve read in looping that Do While...Loop is the fastest and
For...Next the slowest but my tests prove otherwise.
I''ve tested:
Do...Loop
Do While...Loop
Do Until...Loop
While...Wend
For...Next
I didn''t think I could do an accurate test with For...Each unless I used a
collection or an array.
I also see conflicting information on string concatenation and
Response.Write
Is this better?
dim str
str = str & "this "
str = str & "that "
str = str & "this and that"
Response.Write str
or this?
dim str
Response.Write "this "
Response.Write "that "
Response.Write "this and that"
I''ve also seen to speed the last one up:
with Response
.Write "this "
.Write "that "
.Write "this and that"
end with
Are there reliable performance tests that can be reviewed?
Does it vary between languages? ASP:VBscript, ASP:JScript, C/C++, Delp
VB, C#

绝对比这更好。
