just FYI, a iSER testing kernel: http://people.redhat.com/dzickus/el5/52.el5/ referenced from this: https://bugzilla.redhat.com/show_bug.cgi?id=234352 has the required one-liner patch to fix mthca, so maybe it'll be fixed in RHEL soon. the 2.6.18-52.el5 kernel + stock CentOS5 userland + the iSER git appears to be fine under testing, and has a tad better read performance than 2.6.22.6 Version 1.03 ------Sequential Output------ --Sequential Input- --Random- -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks-- x11 1G 78579 99 417268 92 208824 34 85054 96 340290 25 +++++ +++ x11 4G 78341 99 446128 96 194134 29 86896 98 343078 25 +++++ +++ x11 6G 78720 99 457873 98 191004 28 86464 97 347046 24 +++++ +++ cheers, robin _______________________________________________ Stgt-devel mailing list [email protected] https://lists.berlios.de/mailman/listinfo/stgt-devel
