The best solution is to upgrade to recently released less-371, which is as fast as less 346 with buffer size patched to 32KB, but in a smarter way (so should scale better I expect, and the buffer size in version 371 is 8KB rather than 32KB, so it should start faster when reading files from slow media (e.g. floppy)) [...] > Have you played with the less command line options > for buffers?

No, -B -bn will reduce memory consumption at a cost of keeping only part of data in memory (i.e. discarding some when reading from pipe) > > -Thomas > Best regards, Wojtek _______________________________________________ Redhat-devel-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-devel-list
