Ensure enough buffers of adequate size
You set the size and number of buffers in the plconfig configuration file with the onpload utility.
For adequate performance, you should provide at least two (preferably
three) AIO and stream buffers per converter thread. The size of AIO
buffers should be at least as large as the device block size, and
the size of the stream buffers should be large (32 or 64 KB), as the following
table shows.
| Configuration Parameter | Size | Comment |
|---|---|---|
| STRMBUFFSIZE | 64 | Should be some multiple of AIOBUFSIZE for best performance |
| STRMBUFFERS | 2 * CONVERTTHREADS | |
| AIOBUFSIZE | 64 | |
| AIOBUFFERS | 2 * CONVERTTHREADS |
