Hi, One of my applications is spending around 90% of total execution time reading a huge file using read system call. I though that I could improve the performance of the application by increasing the page size for kernel heap. I know that I can increase page size of application heap using ppgsz command on the fly. But I don't know how to change the page size for kernel heap. Could anyone tell me if there is any command for this or is it possible through kdb/adb, please?
My machine is a multi-core AMD Opteron running OpenSolaris.2009.06. File system is ZFS. And also please let me know if there are any ideas (tunable parameters) to improve the File IO on ZFS. Thank you. Best, Kishore -- This message posted from opensolaris.org _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
