Logic Pro 9.1.7 in 32 bit gets very slow when using Plugin Alliance Plugins.

Hello, when i use Logic Pro 9.1.7 in 32 bit mode its response gets really slow after opening a few instances of the new Plug-In alliance plugins. I noticed that especially Maag EQ4 and SPL ones cause this problem. If i use it in 64 bit mode it works fine, but i would prefer to use it in 32 bit for the more stability and other reasons like Rewire and Export to movie funcions.

I wonder if anyone else has the same issue. Previous logic version 9.1.6 had the same problem
