You're probably right, but for now RAID 0 performance is enough for me on modern HDDs, I have no problem with my desktop setup I use for working, the problem is getting a mobile setup that won't be 5 times slower and I don't think SSD in a laptop will help THAT much. >> As I'm writing these words, Netbeans and Glassfish running for some 3 or >> 4 hours take 2,5GB of my memory and it grows with each redeploy, max >> I've seen was almost 8GB.

That's actually quite strange with Netbeans. I can see it's using Xmx 512M and MaxPermSize 200M but it still takes up almost 800M in mem and I've seen more than 1,5G occasionally. As to Glassfish - I have plenty of RAM so I upped Xmx and permsize because otherwise it would give me outofmemory exceptions every 2 or 3 redeploys. I guess it's some serious leak in Glassfish itself, because it happens for more than one apps and at the production, where redeploys are rare, the problem is nonexistent. > You wont note a difference betwenn i5 and i7 when developing webapps. > If you do care about build time differences of a half second then use > a i7. Probably true because I don't see all cores of my i7 busy too much on my desktop (video and mass image processing is amazingly fast though). So, a laptop with i5, 8G of RAM and an SSD drive perhaps should be good for my needs. I haven't been really following _all_ tech changes in PCs recently, is there anything else I should look at when hunting for a perfect machine? :-) ------------------------------------------------------------------------------ Gaining the trust of online customers is vital for the success of any company that requires sensitive data to be transmitted over the Web.
