Presumably you're using exactly the same MIB module code in both cases? > [I] am at a loss as to why the times are so far off. The internal architecture of the agent changed quite significantly between the v4 and v5 lines. Although the v5 agent includes an "old_api" handler, to retain backwards compatibility, this is not a particularly efficient mechanism, so there is a significant overhead when compared with the v4 agent. If performance is a significant concern (and for a table of that size, this seems very likely!), then you should seriously consider re-working the module implementation to use the native v5 handler approach. That would definitely get you a significant speed improvement (depending on the helper framework you used) - probably comparable to (if not better than) the v4 agent.
