Issue/Introduction

Will increasing the value of BLOCKSIZE help throughput in any meaningful way?  How do we size for this parameter on the SYSGEN NODE statement?

Resolution

Not sure if increasing the blocksize will help. It depends on the size of the records that you are sending. You need to be sure that the BLOCKSIZE is large enough to hold the largest record size plus a few bytes for our control characters. Generally, 8192 is a good blocksize, which is the default value. Some applications have data lengths that are extreme, but 8192 is usually sufficient.
