Hi,
Just thought I would share something I discovered this week. We were suffering real performance issues with Mono and Informix, we were seeing what appeared to be threads blocking in SQL operations. Even configuring unixODBC for threads did not give anywhere near the same performance as comparable tests using seperate isql processes. I found that it was possible to point /etc/mono/config to use an Informix Odbc library directly however this meant some calls failed (SQLError) with Entry Point Not Found exceptions. I found that Informix had split functions across two libraries. So I created a 'wrapper library' ld -shared -o informix_wrapper.so /opt/IBM/informix/lib/cli/iclit09b.so /opt/IBM/informix/lib/cli/idmrs09a.so And updated /etc/mono/config <!-- <dllmap dll="i:odbc32.dll" target="libodbc.so" os="!windows"/> --> <dllmap dll="i:odbc32.dll" target="informix_wrapper.so" os="!windows"/> This has resulted in much better performance and I no longer see threads blocking each other in SQL functions. I know a couple of other people on this list are using Informix and Mono, hopefully you may find this useful.
