Have you done any benchmarking that shows this is a good idea? My own thoughts on the subject have been along the line that pages for different slru logs possibly need to be different sizes, so that eg we could have more than 2K subtransactions per page. I'm not sure this is worthwhile (is there any place in slru.c that depends on a fixed page size for efficiency?) but it needs to be considered before we make purely cosmetic changes in the area. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
