Hi there, I am currently iterating over somewhere between 7000 and 10000 text definitions varying in size between 0 and 5000 characters and I want to check whether a particular string exists in any of them. I want to do this for somewhere in the region of 5000 different string definitions. In most cases I just want to to know an exact ...
When building our Java applications in Eclipse, the Spring builder is very slow and gives no status updates. Specifically, I start building a project, and Eclipse's Progress pane displays Invoking 'Spring Project Builder' on 'project name'... for multiple minutes at a time, with no additional details. I've already turned off the ...
Hey all, We're using POV-Ray to generate some 80 images per run, which we stitch together to form two moving GIF files (two 360 degree views of a scene). We're looking for ways to speed-up this image creation (on a headless linux server) as much as possible, as they'll be displayed on a webpage directly following creation. Now I know ...
I have the following code in a controller user = RegUser.create_reg_user(:some_parameters) UserStuff.pass_user(some_parameters) @hex = user.hex The @hex is passed to the view and returned. The UserStuff call is taking a decent amount of time and is not actually important to the @hex which is needed for the view. Is there a way to go...
Hello, I'm very new to performance engineering, so I have a very basic question. I'm working in a client-server system that uses SQL server backend. The application is a huge tax-related application that requires testing performance at peak load. Meaning that there should be like 10 million tax returns in the system when we run scenari...

I watched old videos that suggest to test the asp.net website load using Microsoft Web Application Stress Tool. But there is a broken link to get the download. Can any body suggest me a tool to test website performance? ...
I assume that public or private static targets must have reduced memory usage, due to the fact that there is only one copy of the static target in memory. It seems like because a method is static that might make the method a potential point for further optimization by the CLR compiler beyond what is possible with a non-static function. ...
Hello, I am currently having heavy performance issues with an application I'm developping in natural language processing. Basically, given texts, it gathers various data and does a bit of number crunching. And for every sentence, it does EXACTLY the same. The algorithms applied to gather the statistics do not evolve with previously rea...

I have a query which joins 6 tables, produces 800,000 rows, and inserts them into a table. I'm running this query on Sql 2005 Standard on an 8-core machine, on which there is no other workload running. The Sql service uses only one CPU core while running this query (using that CPU for 100%), and this way the query runs for almost 4 minu...
I have two large identical-sized files. One is ASCII plain text, and the other is a colour-coded overlay, one byte per text character in the corresponding file. These files can be large - upto 2.5 MB; possibly substantially more, perhaps over 100MB later. I want to display the text is a scrollable text viewer, using the second file as...

Now is there any way by which we could update the existing upside without taking it offline ...
Hi all, I was looking for an online example demonstrating a timer in ruby and came across the code below. It works as expected but does it make sense that this simple program uses 30Mo of memory (as shown in windows task manager) and way too much CPU? Thanks a lot def time_block start_time = Time.now Thread.new { yield } Time.now...

I've been poking around mscorlib to see how the generic collection optimized their enumerators and I stumbled on this: // in List<T>.Enumerator<T> public bool MoveNext() { List<T> list = this.list; if ((this.version == list._version) && (this.index < list._size)) { this.current = list._items[this.index]; this...
Hello, I'm working on a project which uses many scripts (Google Maps, jQuery, jQuery plugins, jQuery UI...). Some pages have almost 350 kB of Javascript. We are concerned about performance and I'm asking myself what is the best way to integrate those heavy scripts. We have 2 solutions: Include all scripts in the head, even if they a...
