Latest news

NEW: JANUARY NEWSLETTER

• We list all the latest Java performance related news and articles
  • "the intention to merge JRockit to HotSpot - surely a good thing as they each have pretty good features that the other lacks. The focus on garbage collection, multi-core processing and real-time monitoring is spot on"
• Javva The Hutt rambles through performance past, present and future
  • "A technical interview on sheets of paper is the first hurdle. Writing code by hand? Is this still the 20th century? Why not punch cards while you are at it?"
• All the latest Java performance tips extracted in concise form
  • "Once you need to call something remotely, you definitely lose time. Saving network calls in either numbers or size will save time."
• A new cartoon by "profiler". This month: Multi-threading code

DECEMBER NEWSLETTER

• We list all the latest Java performance related news and articles
  • "Also worth mentioning is what didn't change this year: multi-core support and increasing concurrency is still where the hot action is; profiling concurrency issues is still the most challenging area of performance; and the performance issues that you encounter are just the same as they have been for years - and they are, in order of decreasing frequency encountered: database access; memory leaks; distributed applications; concurrency; garbage collection."
• Javva The Hutt rambles through performance past, present and future
  • "Too expert? Too senior? Am I living in some bizarre world where 'you look like you can do the job fairly easily' translates into 'we don't want you'?"
• All the latest Java performance tips extracted in concise form
  • "Two alternative approaches to handle combining realtime graphs are: Pull On Demand - gather all data when a request is initiated by a user (this is easier to program and more suited to the web, but limits scalability); and Push on Change - any change is pushed out to all interested users and held until the user requests to view updates (so making that last action very fast)."

How to use this site

This site has four main information resources:

• The uncategorized tips page lists many other web pages with Java performance tuning related information. Each web page has its performance tuning tips extracted and listed immediately after the URL is listed. These tips are being categorized, and the tips page links to those categories currently available. If the performance area you are interested in is not yet categorized, send us an email from this page telling us the categorization you'd like to see. In any of the tips pages, use your browser's "find" or "search" option to identify particular tips you are interested in on the page, and follow up by reading the referenced web page if necessary or desired.
• The resources page lists Java performance tuning resources including books, tools, reports, other performance tuning sites of interest, and Java performance tuning discussion groups.
• The news pages are monthly newsletters listing any new Java performance tuning related information, together with Kirk Pepperdine's discussion group roundup and Javva The Hutt.
• The tool reports pages are detailed introductory reports on various Java performance related tools, for both free and commercial tools.

This site has been designed to download almost as fast as possible. (Some stylistic markup and required server-side processing has been used in preference to absolute speed contraints.) The web tree contains very few graphics and almost no complex typesetting markup except for very simple tables, and the main pages can be accessed directly from the menu.
