Martin Svec 8f67835f1e target/rd: improve sg_table lookup scalability ... Sequential scan of rd_dev->sg_table_array in rd_get_sg_table is a serious I/O performance bottleneck for large rd LUNs. Fix this by computing the sg_table index directly from page offset because all sg_tables (except the last one) have the same number of pages. Tested with 90 GiB rd_mcp LUN, where the patch improved maximal random R/W IOPS by more than 100-150%, depending on actual hardware and SAN setup.
