I’ve mentioned before about how the sync_binlog setting in MySQL can be especially slow on ext3. Of course, I wasn’t the first to discover this; the MySQL Performance Blog mentioned it months ago. I was reading through some of the slides I mentioned in my last post, and remembered that I’d left sync_binlog off on [...]
I enabled APC, the Alternative PHP Cache, a while back. The basic premise is that it’s an opcode cacher, making up for the fact that PHP pages get compiled on each pageload. It also caches oft-used files, though. (Although, in theory, Linux ought to be caching oft-used files in RAM too, APC is a bit [...]
A really random thought just popped into my head… UNIX systems have their “swap” partition, a disk partition where unused stuff in RAM is “swapped out” to disk to make room for newer stuff in RAM. Of course, no hard drive is as fast as RAM, so you obviously want lots of RAM so you [...]
I think I’ve alluded earlier to the fact that I’ve been trying to speed up some systems at home, and how some of them are really slow. (I’m starting to suspect Norton, actually, but more on that when I find out more.) I just came across this spiffy application, which will write and then read [...]
