Hi,
I recently measured some load and filter times with and without a LUA
postdissector plugin called TRANSUM. I tried three different scenarios:
* No LUA - without any plugins other than those shipped as standard
* Bypassed LUA - with TRANSUM but a preference set so that on entry to
the postdissector immediately returns to Wireshark
* LUA Enabled - with TRANSUM enabled
The test file was a 47MB pcapng file with mostly web traffic. Almost all of
the data packets would have been scrutinised by TRANSUM in some detail.
I timed loading the file and then filtering with the expresssion tcp.len>0.
The timings were:
No LUA
Bypassed LUA
LUA Enabled
Load of file
1.0s
2.5s
5.4s
Filter with tcp.len>0
1.7s
2.9s
5.2s
The thing that surprised me was the impact of just having the LUA loaded, even
if it immediately returned to Wireshak (the Bypassed LUA scenario).
Not a problem - just an observation.
Best regards...Paul
