[Lift] Re: What a difference a CPU makes
I've wanted to try a solid-state disk for a while. All but the cheapest systems you can buy these days are Core 2 Duo with 2+ GB of decently fast RAM (i.e. you can get a decent dual-core laptop with 2 GB of RAM that will run Ubuntu like a champ for ~$500). It seems like the real way to boost performance on a machine like that is to get a much faster disk.

Derek, What OS are you running? The old numbers are worse than my HP 2133 Netbook which clocks in at 15 minutes for a full Lift build.

[Lift] Re: What a difference a CPU makes
Ubuntu 8.10 x64. Java is java version "1.6.0_12" Java(TM) SE Runtime Environment (build 1.6.0_12-b04) Java HotSpot(TM) 64-Bit Server VM (build 11.2-b01, mixed mode) Here's AMD's rundown of the difference between the CPUs: http://products.amd.com/en-us/DesktopCPUSideBySide.aspx?id=522&id=59 Note that I'm still using the original AM2 motherboard with the same DDR2-800 memory. The fact that it's AM2 means that the Phenom is downgrading its HyperTransport to the same speed as the Athlon X2 for bus access. I suppose I could benchmark it to see how it performs for other tasks. I'm not sure how much an SSD would help. I'll run a build and monitor iostat to see how much data transfer goes to/from the HDDs, but my machine typically runs a file cache of about 800-900MB of memory (6GB total), so I would suspect that most of what maven needs gets sucked into the cache.

Weird. My 2133 is running at 1.2 Ghz and has an 800Mhz (at best) memory speed. My experience with Lift builds on machines with a lot of memory is that there's almost no disk access... everything is cached.

[Lift] Re: What a difference a CPU makes
Yeah, the iostat indicates very little disk activity, and since my machine is running servers for web, email and VPN what I'm seeing could be entirely unrelated to the build. As a comparison, my laptop (Dell Precision M4300) with an Intel Core Duo T7700 and 4GB of memory builds in about 8:30. That's a 32-bit JVM, so maybe I should run 32 bit on my desktop to see if that makes a difference. My suspicion is that because the Athlon X2 4200+ has no L3 cache (128K L1, 512K L2) it's having to go to main memory a lot. The T7700 has 4MB L2 per core and the Phenom has 6MB L3 shared across cores. How does my current 7 minute build time compare with other people's experience?
