Every time you refresh left_main.php * session is locked till page is loaded. You can't load other scripts. * SquirrelMail executes 'left_main_before' and 'left_main_after' hooks. Speed depends on plugins attached to these hooks. newmail, filters, quota, some other plugins. * IMAP status command is executed on every monitored folder. Speed depends on number of folders with message counters displayed on the right side. SquirrelMail 1.5.1 has some optimizations in this part of code. Other commands are pretty standard. IMAP login, logout, page generation Check options provided by folder_synch plugin. -- Tomas ------------------------------------------------------------------------- Take Surveys. Earn Cash.
