Hi, take a fresh 3.10 7081: 16MB Update is to 7091: 36MB I follow the update process to determine what took that much space: - Update 7087 takes 6MB (http://ftp.squeak.org/updates/7087TallySupport.cs) - Just before saving the image size is 23MB - Just after saving it is 36MB Does someone have any idea? -- Damien Cassou
