Table 2.4:
Flow Options
| Option |
Description |
|---|
| memcap |
Number of bytes to allocate. |
| rows |
Number of rows for the flow hash table. 1 |
| stats_interval |
Interval (in seconds) to dump statistics to STDOUT. Set this to 0 to disable. |
| hash |
Hashing method to use.2 |
|
- 1 This number can be increased, at the cost of using more memory, to enhance performance. Increasing rows provides a larger hash table.
- 2 1 - hash by byte, 2 - hash by integer (faster, not as much of a chance to become diverse). The hash table has a pseudo-random salt picked to make algorithmic complexity attacks much more difficult.
