I made some additional research: what need a lot of the memory is the spell checker. If you dont have spell checkers, when you open the first mail to write, the memory does not jump. If you do have spell checkers, they will -of course- loaded into the memory and stays there. I must have many selected on my other machine so my VM size jumps to 130 MB or so, on this PC it is "only" 70 MB. I have to check if the SSCE or the Hunspell or the CSAPI is the most memory consuming. I think, it is not a memory leak, it is just the way TB works. However, I have to test, why Voyager works differently...
Anyway, also another observation: if you open up 10 mail editor window (Ctrl+N) and close them (Esc), the memory usage increases. Do it repetatively, and the free mem just shrinking and shrinking... It is obviously a memory leak that should be fixed. It seems like 12 kB/mail is the leak. Another memory leak: hit Ctrl+Shift+Q, Quick Templates. Then close the window. Do it many times. Memory usage is increasing with all replicates. Memory leak... Another memory leak: Tabs in the mail list. I have the All, Unread, and 3 others based on View modes. If I click on them randomly, waiting 1-2 sec, the memory consumption increasing... Not that much, but there is a leak here, too. It seems, that the mem. usage goes up when I click back to the All tab... If you dont see mem. increase, just click around more... Another 4k/repetition leak: SmartBat. F6, wait a sec, Esc, mem. usages is up by 4 kB. And this little leaks adds up big. I am pretty sure, more could be found... Also: number of threads. At first, I have 27. Open the 10 mail and close them, they jump to 35. Download the mails from an account, increases it with one, one per account. I dont know, why threads are not terminated... Maybe there is an optimization reason. So, I think, before any additional work, Ritlabs should go thru the code and CLEAN IT, looking for memory leaks... -- Vili ________________________________________________________ Current beta is 4.0.20.2 | 'Using TBBETA' information: http://www.silverstones.com/thebat/TBUDLInfo.html
