堆内存使用Openssl

Question

我在C中使用Openssl库实现了一个简单的HTTPS服务器。单个连接的堆使用量似乎很大。以下是一些可能占用大堆空间的对象：

• char readbuffer[8192]
• SSL_CTX
• SSL

这是正常的吗？有没有一个工具可以找出哪个对象需要多少堆？

Answer 1

尝试确定哪些malloc调用以及何时调用。 Dmalloc可以提供帮助：http://dmalloc.com/

有一次我还使用了一个简单的包装器脚本来手动跟踪内存分配。我认为就是这个： http://www.cs.cmu.edu/afs/cs.cmu.edu/academic/class/15213-s03/src/interposition/mymalloc.c
