[LAU] vsts and wine startup times

I have been playing around with a new program that does win->linux vsts called airwave. It seems pretty nice as it does xembed properly so all menus etc. appear correctly, and the vst performance seems acceptable (fewer xruns than vst-bridge). I hit a problem when first running it which turned out that it was due to the host not waiting long enough for the vst to initialise. It hard coded a maximum wait of 3 seconds.. Whereas on my system, wine takes around 24 seconds to start first time or around 4 seconds on subsequent times. I have been in discussion with the dev about increasing the timeout. He changed it to 8s which works OK apart from first run on my system. So my questions: 1) what is the longest startup time for wine that would be reasonable to assume? 2) is 24 seconds abnormal for a reasonably recent (last 3years - AMD A6-3670 ) desktop system? James
