Re: Is cygwin much slower on Core 2 Duo
nope. here's the thread from a while ago:
Thanks for the replies. I somehow managed to miss this big thread from a
few weeks back (maybe because the spelling was DualCore(s), as one word,
Anyway, after reading all that, and some more related posts that I
found, I decided to completely remove the firewall. I have been using
Kerio PFW for a few years. Prior to that I used to run with ZoneAlarm
and then Symantec, both of which I ditched for various reasons. Kerio
used to be an excellent firewall. It is is even somewhat recommended in
the Cygwin FAQ.
However, a couple of months back I noticed something strange when
connecting to various unix machines over ssh. It would take over five
minutes to start vim or mc on the connected machine. This hadn't
happened before. I couldn't see anything when trying to trace on
processes or the network traffic. When disabling the "Network security
module" in the firewall it would go away. I contacted Sunbelt support
(the new owners) and after some extra data gathering nothing happened.
Since then I have updated the firewall twice, currently I have the
latest release. I things have been worse than ever.
Anyway, today I removed the Sunbelt Personal Firewall (as it's called
now), and tried reinstalling PHP 5.2.2. (This might seem a bit odd, but
it can serve as a benchmark here. The installation creates subshells at
least four levels deep.) Before, as I wrote, it took 43 minutes. Now
after removing the firewall it takes 10 minutes. When disabling
antivirus (Kaspersky) it takes less than 5 minutes. My computer is
Even some other minor oddities when booting up seem to be gone. Overall,
things seem to back to normal again. Except now I have to find a working
firewall again. Any recommendations anyone?
Conclusion: It would seem that Sunbelt have majorly screwed up the old
Kerio Personal Firewall. It does not seem fit to be used with Cygwin
anymore. I even question its usefulness altogether because I suddenly
lately have had a *lot* of minor strange things happening on my
computer. It's too early to tell if they are completely gone now though.
