Do you mean checking the hash result against a known value, or doing a digital signature (e.g. RSA/ECDSA) verification?
I think that these benchmark results are for a long stream of data, so you may wish to apply them with a grain of salt when guessing the time taken to hash just 32KB. But if you look at MiB/Second (mebibyte/sec basically megabyte/sec), this might give you a rough idea of the speed. e.g. SHA-256 does about 81 MB/sec, assuming you can keep it fed with data that fast. The rest is just maths - 81MB/sec is (81*32) * 32KB/sec, so you might be able to do about 2400 such hashes per second - although there will be more overhead in doing 2400 small chunks of 32 KB than in doing one chunk of 81MB.
