Folks, the OP said:
30Mbits/sec

That's "bits", not "Bytes"!

In bytes, that's around 3.333 MB/s.

Which is fine with most current hardware. 40000 records/sec means nothing: what we need to know is how many bytes/rec on average, and how many rows can be batched into a single write operation. Received on Wed Feb 08 2006 - 12:57:39 CET
