I have a working net-snmp application, with my own MIB.
My MIB has a number of statically-sized tables. I have increased the
size of one of those tables to 10,000 rows. (It was less than 1000 rows
previously).
At start-up, my code executes
entry = SNMP_MALLOC_TYPEDEF (struct my_table);
row = netsnmp_tdata_create_row ();
...
netsnmp_tdata_row_add_index (row, ASN_INTEGER, &entry->item, sizeof
(item));
netsnmp_tdata_add_row (table_data, row);
for each row. This takes a long time - about 30 seconds.
(The table is read-only. It has about half a dozen columns, each of
which is a simple integer or truth value. The index is the first column,
which is not-accessible. The 'my_table' struct only has the index value
in it; SNMP 'get's use the index to retrieve the actual data from the
application.)
Is there a way to reduce the time it takes to create this table?
(Putting in log statements, e.g. after every 1000 rows, shows the
insertion to be taking order-N^2 time. Would inserting the rows
backwards make any difference?)
net-snmp version: v5.3.0.1. (I am considering updating to a newer
version. But that won't necessarily solve this issue.)
