Package: snmp Version: 5.7.3+dfsg-5+deb10u1 Severity: normal Dear Maintainer,
Since last snmp release 5.7.3+dfsg-5+deb10u1, we detected performance regressions on snmpget/walk/bulkwalk (probably all commands). We bisected the regression to this patch: https://github.com/net-snmp/net-snmp/commit/4fd9a450444a434a993bc72f7c3486ccce41f602 For snmpd daemon, performance impact is probably very slow, the .index file was not mandatory. However, for our use case (monitoring application) running a lot of snmp commands, strace show a big change on number of opened files: grep -c openat snmpget_strace_before 55 And now: grep -c openat snmpget_strace_new 2197 We are looking for workaround (or to accept this drawback), but if you have a solution to restore this cache for snmp commands only (probably not affected by security issues like snmpd), it would be greatly appreciated.
