MySQL PBXT vs InnoDB
I'm wondering what are are the pros/cons of the new PBXT Engine vs the good old one InnoDB? Where can I find a list of features and maybe some benchmarks comparing these two DB engines? ...
Help me understand apache ab
I did a few Google search, but found no explanation of how it actually performs stress tests. As far as I understand, concurrency means simultaneous number of connections. ab probably starts the given "c" number of connections at the very same time, and hold back the following waves until all requests are fulfilled. Am I right? Given ...

How can i benchmark my SQL and PHP code?
I have problems because i don't really know how I can test my code and sql ( mysql ) to see how long SQL queries and PHP functions /code take to run. Does anyone here know where I can find these tools? ...
Benchmarking: When can I stop making measurements?
I have a series of functions that are all designed to do the same thing. The same inputs produce the same outputs, but the time that it takes to do them varies by function. I want to determine which one is 'fastest', and I want to have some confidence that my measurement is 'statistically significant'. Perusing Wikipedia and the inte...
What is the fastest Ruby logger implementation?
I want to find the fastest logger Ruby has to offer. My intuition tells me that syslog would win in this race. But my intuition seems to be wrong. Syslog turns out to be the slowest out of the three loggers I've tested. I'm using my MacBook Pro, OSX 10.6 (Snow Leopard), Intel Core2 Duo, 4GB of RAM and Ruby 1.8.7 built from MacPorts. ...
Software for benchmarking a slow site?
I have a homegrown CMS running on multiple ISPs. End users have complained that viewing and administering their sites is slow. We suspect the problem is with different ISPs/server that we use. I am trying to determine a benchmark so I can look for a better/more consistent hosting option. To do so - I need data. My goal is measuring load...
Can someone please explain what these ApacheBench results mean?
Hi folks, i'm trying to figure out how to use ApacheBench and benchmark my website. I installed the default site project (it's ASP.NET MVC but please don't put stop reading if u're not a .NET person). I didn't change anything. Add new project. Set confuration to RELEASE. Run without Debug. (so it's in LIVE mode). Yes, this is with the ...
Why are two Java threads (in some cases) more than twice as fast as one?
File: Example1.java public class Example1 implements Runnable { public void run() { for(int i = 0; i < 100000000; i++) { int x = 5; x = x * 4; x = x % 3; x = x + 9000; x = x * 923; } } public static void task() { for(int i = 0; i < 100000000; i++) { int x = 5; x = x ...
Tools to benchmark web-services
What tools are best for measuring web-services performance? It would be nice to get report for total transferred data, total POSTs, requests per second, time per request, transfer rate and response time per request. ...
HTTPS vs HTTP speed comparison
I'm considered running my entire e-commerce website under https. I decided to run a crude benchmark to measure the download time of a 156KB image through https vs http because I had read that https is burdened with additional overhead from the encryption process. Benchmark was performed using Firefox's Firebug simply by transcribing the...
Comparing CPU speed likely improvements for business hardware upgrade justification
I have c# Console app, Monte Carlo simulation entirely CPU bound, execution time is inversely proportional to the number of dedicated threads/cores available (I keep a 1:1 ratio between cores/threads). It currently runs daily on: AMD Opteron 275 @ 2.21 GHz (4 core) The app is multithread using 3 threads, the 4th thread is for another...
Benchmarks of code generated by different g++ versions
I work on a runtime system for an application domain that is very performance sensitive. We go to a lot of effort to maintain backward compatibility with older compiler versions, including avoiding more recently-implemented language constructs, and synthesizing them for the older versions. However, I'm concerned that this effort does a ...

C#: Is this benchmarking class accurate?
I created a simple class to benchmark some methods of mine. But is it accurate? I am kind of new to benchmarking, timing, et cetera, so thought I could ask for some feedback here. Also, if it is good, maybe somebody else can make use of it as well :) public sealed class Benchmark : IEnumerable<long> { private readonly Action subject...
Writing a time function in Haskell
I'm new to Haskell and I'd like to be able to time the runtime of a given function call or snippet of code. In Clojure I can use 'time': user=> (time (apply * (range 2 10000))) "Elapsed time: 289.795 msecs" 2846259680917054518906413212119868890148051... In Scala, I can define the function myself: scala> def time[T](code : => T) = {...
