Hi, I guess this question should be a faq but I haven't found any recent document/paper explaining the performance penalties implied by a typical small-scenario LVM installation. In particular I have a SuSE 8 linux in a 1 GHz processor box, with a 13 gb "normal" ide disk. I have another hd that, if necessary, I will use in a future to expand partitions. So I had thought of using LVM (scalability purposes). But before installing it, I'd like to have a look to any recent paper/doc/article talking about the performance of LVM. Beside this, I'd also like to know about the performance of a LVM over (software-) RAID system. Is there any kind of comparative or benchmarking about typical IDE systems with LVM (recent version) (and with/without RAID)? Ups, I forgot it: I'm always refering to LVM in linear mode (non-stripped mode), with each disk containing one PV. Summarizing: Which % of penalty will I suffer if I install LVM? Which kind of operations would be more affected? I read about 1% penalty and "dd" operations being the worst cases. Could you confirm it? Thanks in advance and sorry if this is a faq...
