Dear Edward Shishkin, May be that my comment might be userfull for your reiser development: I am facing following performance issue. The reiser works without data loss, but system sometimes hangs for 15s, mouse cursor is frozen and after this period it continues to work without any problem. It is strange, because I have 6 cores and all of them seems to be locked and waiting for something. Hanging occurs during intensive file search like find, or first phase of rsync. It seems to me that both reiser3 and reiser4 suffer by this issue. I have found BKL inside reiser3, but reiser4 seems to be without BKL. It is also strange that OS resides on different partition that should not be affected by reiser locking. May be that it could be problem large say 600GB HDD partition. But these partitins are normal nowadays. Is there any idea how to overcome this issue? best regards Jara -- To unsubscribe from this list: send the line "unsubscribe reiserfs-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
