c# - GetType() == type perfomance question -

-

I am making an XNA game and I am calling the following updates 2 to 20 times the code. I tried googling and it seems that it is half slow, so I thought I was asking what kind of fast way to compare the type?

code: 

  Public modifier for this [type type] {for (int i = 0; i & lt; this.Qount; i ++) {if ( It [I.] Type GETType () ==) {Please return this [ii]; }} New NotImplementedException Throw ("Fix It"); } Set {for (int i = 0; i & lt; this.Qount; i ++) {if (this [i]. Type GetType () ==) {this [i] = value; }} If (System. Diagnostics.Debugor.ISAcredited) system. Diagnostics. Debugger. Break (); }}   
 This code is in the modifier collection section which comes from a list. The modifier is a part of the particle engine. In addition, my game is not in a situation where I can actually do this test, so I can not test it, but should it work right?  
 I read something about runtime typhanies, which is fast, should I use it?  
 Thanks a lot!  
 Edit: What I'm aiming to do with it is that I can do the following:  
  (particleEffect ["nameOfEmitter"]. Audifier [typef (Some basic modifier)] as some basic modifier. Variable = value;   
 Actually I just want to change the value of some modifiers in the runtime.  
 2 Edit: I Realized that I can only save the modifier's reference in the classroom where I am currently calling it P: Maybe I do not have a clean code when I have 5-10 modifiers, but this problem should be removed. 
 
 
 if You do not need any additional functionality that is made known to you by  type , and you only relate to full equality between types - that is, you do not need it - Support legacy -  runtime typing handles < / Code> This is the fastest way to compare.  
 In fact, But, I question that this is not the weakness of your classroom design. Unless you have a compelling reason to examine the type directly, then it may be better to expose some types of value (possibly an enum) on your objects , Which they are, and compare it against you.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

memcached - Django cache performance -

-
We are now using Redis for in-memory cache for our Django application (we used the first memcatch The difference in performance is no big, and we're using Redis because the disc dump feature). The problem is that Django cache's performance in my view - terrible, we have a view with 102 cache hits (no miss), and it has 81 ms (only the cash part, which is with the DJBugBug toolbar Is measured). In my opinion - this is a very long time, I know, asking for a question for DB can be 10x more (or 100x) time, but that is also not good with cash performance of that fact. We are running radis (and the first memacatch) on different hosts, connected to the local network with other servers. Is there a way to maximize cache performance in Django? Instead of displaying problem cache, there is a possibility of the number of items to be received for each page 102 Cash calls mean long time lost due to network latency. With full control of the code, you may be able to fix it with m...
