| jpayne@69 | 8 Description: Benchmarks a disk with multithreaded I/O. |
| jpayne@69 | 9 |
| jpayne@69 | 10 Usage: diskbench.sh path=<path> data=<8g> passes=<2> threads=<> |
| jpayne@69 | 11 |
| jpayne@69 | 12 Parameters: |
| jpayne@69 | 13 path= Location to read and write. |
| jpayne@69 | 14 data=8g Number of bytes to process per pass. |
| jpayne@69 | 15 threads= Number of threads to use. By default, all logical threads. |
| jpayne@69 | 16 In RW mode the number of active threads is doubled. |
| jpayne@69 | 17 mode=rw I/O mode: |
| jpayne@69 | 18 r: Test read speed only. |
| jpayne@69 | 19 w: Test write speed only. |
| jpayne@69 | 20 rw: Test read and write speed simultaneously. |
| jpayne@69 | 21 |
| jpayne@69 | 22 Processing parameters: |
| jpayne@69 | 23 None yet! |
| jpayne@69 | 24 |
| jpayne@69 | 25 Java Parameters: |
| jpayne@69 | 26 -Xmx This will set Java's memory usage, overriding autodetection. |
| jpayne@69 | 27 -Xmx20g will specify 20 gigs of RAM, and -Xmx200m will |
| jpayne@69 | 28 specify 200 megs. The max is typically 85% of physical memory. |
| jpayne@69 | 29 -eoom This flag will cause the process to exit if an out-of-memory |
| jpayne@69 | 30 exception occurs. Requires Java 8u92+. |
| jpayne@69 | 31 -da Disable assertions. |
