As promised yesterday, I did the JS benchmarks again on a Windows machine so I could include Google Chrome. I tried to be pretty inclusive, adding in IE7, IE8 beta 2, Firefox 3.0.1 (current release), Firefox 3.1 with and without JIT, Safari 3.1 (current release), Safari 4 beta, Opera 9.5 and Chrome. This was all run on my workstation, a 4-core, 3.2 GHz box with 8 GB of RAM. Any add-ons, extensions were disabled. Here ...

Because I've been a bad, bad blogger of late - blame my life: there was a hell of a lot happening in July-August, most of which I can't go into detail about - there have been quite a few performances I've attended recently that I haven't had time to blog about: until now. Apologies for the brevity of the following 'reviews' (perhaps 'impressions' would be a better word); I've got rather a lot to catch ...

Just how fast is Google’s Chrome browser? JavaScript performance-lover (and Mozilla employee) John Resig ran some tests that show Chrome may be fast, but other browsers aren’t that far behind. When Google released Chrome, it included benchmarks that show its browser zipping away from the competition at light speed. There’s no doubt Chrome is fast and we think it’s already changed the web. It seems, like with most statistics, it all depends whose benchmarks you ...

Brendan Eich jumped right in and benchmarked the tip of tree for TraceMonkey, with the V8 version that came with Google Chrome: We win on the bit-banging, string, and regular expression benchmarks. We are around 4x faster at the SunSpider micro-benchmarks than V8. This graph does show V8 cleaning our clock on a couple of recursion-heavy tests. We have a plan, to trace recursion (not just tail recursion). We simply haven't had enough hours in ...

A new JavaScript Engine has hit the pavement running: The new V8 engine (powering the brand-new Google Chrome browser). There are now a ton of JavaScript engines on the market (even when you only look at the ones being actively used in browsers): JavaScriptCore: The engine that powers Safari/WebKit (up until Safari 3.1). SquirrelFish: The engine used by Safari 4.0. Note: The latest WebKit nightly for Windows crashes on Dromaeo, so it's passed for now. ...

A question I get asked occasionally is; "How many IOPS can my RAID group sustain?" in relation to Enterprise class arrays.Obviously the first question is to determine what the data profile is, however if it isn't known, then assume the I/O will be 100% random. If all the I/O is random, then each I/O request will require a seek (move the head to the right cylinder on the disk) and the disk to rotate to ...

In my previous post, I introduced the concept of "persistent vectors" and walked through one implementation of the idea. When I actually pushed the post out, I was pretty happy with my code, but it seems I still have much to learn. :-) A number of very smart people replied, suggesting ways that the implementation could be cleaned up and improved. Among these intrepid commenters was David MacIver, who correctly pointed out the similarities between ...

As you know, i always like to reduce unnecessary roundtrips. With my Request/Response service layer and my QueryBatcher for NHibernate, it’s trivially easy to do so. But what if you’re in a situation where you can’t use NHibernate and are stuck with low-level SqlCommands? It’s actually not hard to enable batching those (select) queries either. (note: for insert/update/delete Commands, there is a better way). People with a lot of straight-up ADO.NET experience probably already know ...

Relational Data Warehouse or Reporting work loads are characterized by low volumes of very large transactions. These applications are often identified as having predominately read workloads (e.g. Decision Support, Analysis, and Reporting) with periodic feeds or batch loads. It is important to keep these characteristics in mind as we examine the significance of database design, resource utilization and system performance. The top performance bottlenecks or gotchas to avoid for Data Warehouse or Reporting applications are ...

Google's new Chrome web browser beta is getting a lot of attention for its slick looks, helpful features, and performance, but how does it rank against the early releases of more established browsers? We've previously put the major browser releases to the speed test, but today we're measuring Chrome against the second beta of Internet Explorer 8, as well as the beta of Firefox 3's next iteration, 3.1.
