The PE1746 is a component on the K6 HSM card. It's use affects performance of the HSM on cryptographic operations, and is controlled by a setting in the Miscellaneous section of the Chrystoki.conf file (Linux and UNIX) or the crystoki.ini file (Windows), like this:
Misc = {
PE1746Enabled = 1;
reconnAtt = 50;
logLen = 262144;
haLog = /usr/safenet/lunaclient/bin/;
}
The bit is on (value = 1) by default.
When it is on, your applications should see higher bulk performance, with lower small-packet performance.
When it is off (value = 0), your applications should see lower bulk performance, with higher small packet performance.
