It consumes substantial amount of cpu ticks reading large directories. This problem was there since 4.x. You can replicate it using Valve's software "steam" content distribution client. ./steam consumes 100% of cpu when updating/fetching files. Until now, we thought that this is steam software problem, but it turned out, that the problem is non existent on Linux (steam consumes ~0-1% cpu). pozdrawiam Tomek "Mathom" Formanowski ---------------------------- PIFPAF.pl - Serwery gier www.pifpaf.pl
