Hi, I recently update a Firebird from 1.5 to 2.1, I did a Backup/Restore, but now the app is slower than before, I though it was something of the indexes, but I rebuild them and it continues. The computer is a 4 CPU processor, 4gb in RAM, is linux Centos 5.5, is a guest machine virtualized with VMWARE. I also updated the clients to match the version.

Any help will be appreciated.
