I don't think there would be any benefit to using InnoDB, at least not from a transaction support view. After your nightly optimize/repair are you also doing a flush? That may help. I haven't seen any direct comparisons between HFS+ and file systems supported by Linux. I would believe that Lin

2GB was the per-process memory limit in Mac OS X 10.2 and earlier. 10.3 increased this to 4GB per-process. I've gotten MySQL running with 3GB of RAM on the G5 previously. This is an excerpt from a prior email to the list from back in October when I was first testing MySQL on the G5: > query_ca

Yes, MySQL is capable of using more than 2GB, but it still must obey the limits of the underlying OS. This means file sizes, memory allocation and whatever else. Have you heard of anybody allocating more the 2GB using OSX? I've heard of quite a bit more using Linux or other Unix flavors, but no

You may be hitting an OSX limit. While you can install more than 2GB on a system, I don't think any one process is allowed to allocated more than 2GB of RAM to itself. It's not a 64-bit OS yet. You should be able to search the Apple website for this limit. On Jan 26, 2004, at 6:10 AM, Adam Gold
