feedback about speedup patches
Hi, I only wanted to give some feedback about the speedup patches: The time to build my maps was reduced by one hour from 3.5 to 2.5 hours. Very impressive.

My first impression is "2.5 hours is a very long time" but it depends on ... - What do you build ? - What do you use (world bounds, world coastlines) ? - What are your hardware resources (number of cores, ram, ...) ? - Which OS are you using ? - ... A finding from yesterday: Using the world coastlines extremely slows down the map building process.

I don't think it makes sense to discuss absolut build times and if this is long or not. As you see on the list above, it depends on a huge amount of other factors. Getting the build time down from 3.5 to 2.5 hours on the same hardware in the same environment is a very big step. And looking at the big amount of data needed for my maps, I don't have the feeling that 2.5 hours are a long time. The hardware isn't the fastest one, and the OS is the newest SLES not yet available on the market, so this will not help you, too ;) Thorsten -- Thorsten Kukuk, Project Manager/Release Manager SLES SUSE LINUX Products GmbH, Maxfeldstr. 5, D-90409 Nuernberg GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer, HRB 16746 (AG Nürnberg)
